Since the Windows console windows use a different encoding than the rest of the system, you must take special care when using 8-bit characters within psql. In general, both will do what you expect, but using -f enables some nice features such as error messages with line numbers. This might not be necessary in HTML, but in LaTeX you must have a complete document wrapper. unaligned format writes all columns of a row on one line, separated by the currently active field separator. The rest of the line is simply passed literally to the shell. Making statements based on opinion; back them up with references or personal experience. If it is not unaligned, it is set to unaligned. $ is not needed as a regular-expression character since the pattern must match the whole name, unlike the usual interpretation of regular expressions (in other words, $ is automatically appended to your pattern). Reserved key words, such as "grant", are never allowed as identifiers. The output of the command (with any trailing newline removed) replaces the backquoted text. It only takes a minute to sign up. This group of commands implements nestable conditional blocks. Lists text search parsers. Unlike most other meta-commands, the entire remainder of the line is always taken to be the argument(s) of \sf, and neither variable interpolation nor backquote expansion are performed in the arguments. If a line number is specified, psql will position the cursor on the specified line of the file or query buffer. If + is appended to the command name, the tables and schemas associated with each publication are shown as well. Lists replication publications. This can be used as a PROMPT2 setting, so that multi-line statements are aligned with the first line, but there is no visible secondary prompt. this form If pattern is specified, only databases whose names match the pattern are listed.

If the separator character appears in a field's value, that field is output within double quotes, following standard CSV rules. Note that you cannot just connect to any database under any user name. Ackermann Function without Recursion or Stack. Executes the current query buffer (like \g) and shows the results in a crosstab grid. *bar* displays all tables whose table name includes bar that are in schemas whose schema name starts with foo. By default, only user-created roles are shown; supply the S modifier to include system roles. So what *is* the Latin word for chocolate? The target width is determined as described under the columns option. The command history is automatically saved when psql exits and is reloaded when psql starts up. This mode is useful if the data wouldn't fit on the screen in the normal horizontal mode. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. The output column identified by colV becomes a vertical header and the output column identified by colH becomes a horizontal header. Within double quotes, paired double quotes reduce to a single double quote in the resulting name. Set the record separator for unaligned output to a zero byte.

Set the field separator for unaligned output to a zero byte. This is set every time you connect to a database (including program start-up), but can be changed or unset. The pager option can also be set to always, which causes the pager to be used for all terminal output regardless of whether it fits on the screen. The database name portion will not be treated as a pattern and must match the name of the currently connected database, else an error will be raised.

Besides what @a_horse_with_no_name says your escaping is causing the problem. Why does the impeller of torque converter sit behind the turbine? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Without an argument, this command shows the current encoding. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. Alternatively, you can keep around a copy of psql from each major version and be sure to use the version that matches the respective server. Thanks for contributing an answer to Database Administrators Stack Exchange! Descriptions for objects can be created with the COMMENT SQL command.

This command is identical to \echo except that the output will be written to the query output channel, as set by \o. By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects. Defaults to the value of the PGPORT environment variable or, if not set, to the port specified at compile time, usually 5432. If only one argument is given, the variable is set to an empty-string value. If no arguments are given, a new connection is made using the same parameters as before.

This output is compatible with the CSV format of the server's COPY command. A schema pattern that contains a dot (.) Specifies the field separator to be used in unaligned output format. To include a single quote in an argument, write two single quotes within single-quoted text. The error rollback mode works by issuing an implicit SAVEPOINT for you, just before each command that is in a transaction block, and then rolling back to the savepoint if the command fails.

Notice the changing prompt: Now we change the prompt to something more interesting: Let's assume you have filled the table with data and want to take a look at it: You can display tables in different ways by using the \pset command: Also, these output format options can be set for just one query by using \g: Here is an example of using the \df command to find only functions with names matching int*pl and whose second argument is of type bigint: When suitable, query results can be shown in a crosstab representation with the \crosstabview command: This second example shows a multiplication table with rows sorted in reverse numerical order and columns with an independent, ascending numerical order. If the current query buffer is empty, the most recently executed query is written instead. Certain variables are special, in that they control psql's behavior or are automatically set to reflect connection state. The best answers are voted up and rise to the top, Not the answer you're looking for? The previous example would be more safely written this way: Variable interpolation will not be performed within quoted SQL literals and identifiers. Lists user mappings (mnemonic: external users). The autocommit-on mode is PostgreSQL's traditional behavior, but autocommit-off is closer to the SQL spec. Lists aggregate functions, together with their return type and the data types they operate on. For example: At the prompt, the user can type in SQL commands. However, psql will waste a connection attempt finding out that the server wants a password. I log into the shell as an administrator using the following details: - Server: localhost - Database: postgres - Port: 5432 - Username: postgres - Password: The port number at which the database server is listening. Learn more about Stack Overflow the company, and our products. But in any case, the arguments of a meta-command cannot continue beyond the end of the line.

These variables are examined in the order listed; the first that is set is used. The GRANT and REVOKE commands are used to set access privileges. Print psql's command line history to filename. On the other hand, the variant using the shell's input redirection is (in theory) guaranteed to yield exactly the same output you would have received had you entered everything by hand. These variables are set at program start-up to reflect psql's version, respectively as a verbose string, a short string (e.g., 9.6.2, 10.1, or 11beta1), and a number (e.g., 90602 or 100001). If pattern is specified, only entries whose name matches the pattern are listed. Here you need to use " because you can escape " (quotation mark or double quote) inside " but you cannot escape ' (apostrophe or single quote) inside '.

If set to preserve-lower or preserve-upper (the default), the completed word will be in the case of the word already entered, but words being completed without anything entered will be in lower or upper case, respectively. If access-method-pattern is specified, only operator families associated with access methods whose names match that pattern are listed. The current client character set encoding. Can I use a vintage derailleur adapter claw on a modern derailleur. Include a trailing space in the value of the variable if there needs to be space between the option name and the line number. When on (the default), each SQL command is automatically committed upon successful completion. Lists foreign servers (mnemonic: external servers).
