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 variables can be set using the SET statement, by editing the
       postgresql.conf configuration file, through the PGOPTIONS environmental variable (when using libpq or a libpq-based application), or
       through command-line flags when starting the postgres server. See Chapter 18, Server Configuration, in the documentation for details.

PARAMETERS

       name
	   The name of a run-time parameter. Available parameters are documented in Chapter 18, Server Configuration, in the documentation 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 parameter can be shown but not set, because the encoding is
	       determined at database creation time.

	   LC_COLLATE
	       Shows the database's locale setting for collation (text ordering). At present, this parameter can be shown but not set, because the
	       setting is determined at database creation time.

	   LC_CTYPE
	       Shows the database's locale setting for character classification. At present, this parameter can be shown but not set, because the
	       setting is determined 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 Section 9.26, "System Administration Functions", in the documentation. Also,
       the pg_settings system view produces the same information.

EXAMPLES

       Show the current setting of the parameter DateStyle:

	   SHOW DateStyle;
	    DateStyle
	   -----------
	    ISO, MDY
	   (1 row)

       Show the current setting of the parameter geqo:

	   SHOW geqo;
	    geqo
	   ------
	    on
	   (1 row)

       Show all settings:

	   SHOW ALL;
		       name	    | setting | 	       description
	   -------------------------+---------+-------------------------------------------------
	    allow_system_table_mods | off     | Allows modifications of the structure of ...
	       .
	       .
	       .
	    xmloption		    | content | Sets whether XML data in implicit parsing ...
	    zero_damaged_pages	    | off     | Continues processing past damaged page headers.
	   (196 rows)
