PostgreSQL GUI tools replace the traditional command-line interface tools used to work with databases. You can also access and navigate your database servers via a Postgres GUI. These GUI tools make administering PostgreSQL deployments easy. PostgreSQL GUI is a management tool for open-source PostgreSQL database users to query, visualize, manipulate, analyze Postgres data. W, -password force password prompt (should happen automatically)įor more information, type "\?" (for internal commands) or "\help" (for SQLĬommands) from within psql, or consult the psql section in the PostgreSQLĪs you can see, the help list contains further commands you can use to get help about specific areas.įor example, you can use psql -help=commands to return a list of commands, or psql -V to return the psql version.Īnd while you’re using psql, you can type \? to get a list of internal commands, or \help to return a list of SQL commands.PostgreSQL is among the most popular database management systems in the world, heavily used by developers for all kinds of big or small applications, ranging from enterprise to personal projects. w, -no-password never prompt for password U, -username=USERNAME database user name (default: "barney") p, -port=PORT database server port (default: "5432") h, -host=HOSTNAME database server host or socket directory (default: "local socket") Set record separator for unaligned output to zero byte Set field separator for unaligned output to zero byte x, -expanded turn on expanded table output T, -table-attr=TEXT set HTML table tag attributes (e.g., width, border) Record separator for unaligned output (default: newline) P, -pset=VAR set printing option VAR to ARG (see \pset command) csv CSV (Comma-Separated Values) table output modeįield separator for unaligned output (default: "|") A, -no-align unaligned table output mode ![]() S, -single-line single-line mode (end of line terminates SQL command) s, -single-step single-step mode (confirm each query) q, -quiet run quietly (no messages, only query output) o, -output=FILENAME send query results to file (or |pipe) n, -no-readline disable enhanced command line editing (readline) L, -log-file=FILENAME send session log to file E, -echo-hidden display queries that internal commands generate e, -echo-queries echo commands sent to server help=variables list special variables, then exit help=commands list backslash commands, then exit X, -no-psqlrc do not read startup file (~/.psqlrc)Įxecute as a single transaction (if non-interactive) V, -version output version information, then exit l, -list list available databases, then exit f, -file=FILENAME execute commands from file, then exit d, -dbname=DBNAME database name to connect to (default: "barney") c, -command=COMMAND run only single command (SQL or internal) and exit ![]() Result: psql is the PostgreSQL interactive terminal. You can type the following to return the help list: psql -help Now that we’ve connected to the music database, we can run SQL queries against it.Įxample: ~ % psql -d music -U barney Here it is again, but this time showing the full terminal input and output: ~ % psql -d music -U barney This connects to the music database using the user called barney. Here’s an example of using psql to connect to a PostgreSQL database: psql -d music -U barney So you can simply open up a terminal window and type psql, or you can type psql, followed an option. The syntax for psql goes like this: psql. For example, you can specify a database to connect to, the user name, a file name to read, and much more. Enter other shell like features to help with administration, scripting, etc.Meta-commands can be useful for administration and scripting. Enter meta-commands (also known as “slash commands” and “backslash commands”).Run commands from a file (instead of standard input).Use SQL to administer users, roles, etc.Create database objects, such as tables, views, indexes, triggers, etc.Psql enables you to administer PostgreSQL from the command line interface (CLI) as an alternative to using a graphical user interface (GUI), such as pgAdmin, Postico, Azure Data Studio, etc. Psql is a terminal based interface for PostgreSQL. ![]()
