SHOW(7) PostgreSQL 18.6 Documentation SHOW(7) NAME SHOW - show the value of a run-time parameter SYNOPSIS SHOW name SHOW ALL DESCRIPTION SHOW will display the current setting of run-time parameters. These vari- ables can be set using the SET statement, by editing the postgresql.conf configuration file, through the PGOPTIONS environmental variable (when us- ing libpq or a libpq-based application), or through command-line flags when starting the postgres server. See Chapter 19 for details. PARAMETERS name The name of a run-time parameter. Available parameters are documented in Chapter 19 and on the SET(7) reference page. In addition, there are a few parameters that can be shown but not set: SERVER_VERSION Shows the server's version number. SERVER_ENCODING Shows the server-side character set encoding. At present, this pa- rameter can be shown but not set, because the encoding is deter- mined at database creation time. IS_SUPERUSER True if the current role has superuser privileges. ALL Show the values of all configuration parameters, with descriptions. NOTES The function current_setting produces equivalent output; see Sec- tion 9.28.1. Also, the pg_settings system view produces the same informa- tion.
