NAME

psql – PostgreSQL interactive terminal

SYNOPSIS

psql [option…] [dbname [username]]

DESCRIPTION

psql is a terminal-based front-end to PostgreSQL. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. Alternatively, input can be from a file. In addition, it provides a number of meta-commands and various shell-like features to facilitate writing scripts and automating a wide variety of tasks.

OPTIONS

-a, –echo-all

Print all nonempty input lines to standard output as they are read. (This does not apply to lines read interactively.) This is equivalent to setting the variable ECHO to all.

-A, –no-align

Switches to unaligned output mode. (The default output mode is otherwise aligned.)

-c command, –command=command

Specifies that psql is to execute one command string, command, and then exit. This is useful in shell scripts. Start-up files (psqlrc and ~/.psqlrc) are ignored with this option.

command must be either a command string that is completely parsable by the server (i.e., it contains no psql-specific features), or a single backslash command. Thus you cannot mix SQL and psql meta-commands with this option. To achieve that, you could pipe the string into psql, for example: echo ‘
