NAME

       DROP CONVERSION - remove a user-defined conversion

SYNOPSIS

       DROP CONVERSION conversion_name
	   [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP CONVERSION removes a previously defined conversion.

       To be able to drop a conversion, you must own the conversion.  "PARAMETERS"

       conversion_name
	      The name of the conversion. The conversion name may be schema-qualified.

       CASCADE

       RESTRICT
	      These key words do not have any effect, since there are no dependencies on conversions.

NOTES

       Use CREATE CONVERSION to create user-defined conversions.

       The privileges required to drop a conversion may be changed in a future release.

EXAMPLES

       To drop the conversion named myname:

       DROP CONVERSION myname;

COMPATIBILITY

       DROP CONVERSION is a PostgreSQL extension.  There is no DROP CONVERSION statement in SQL99.

NAME

       ALTER_CONVERSION - change the definition of a conversion

SYNOPSIS

       ALTER CONVERSION name RENAME TO new_name
       ALTER CONVERSION name OWNER TO new_owner
       ALTER CONVERSION name SET SCHEMA new_schema

DESCRIPTION

       ALTER CONVERSION changes the definition of a conversion.

       You must own the conversion to use ALTER CONVERSION. To alter the owner, you must also be a direct or indirect member of the new owning
       role, and that role must have CREATE privilege on the conversion's schema. (These restrictions enforce that altering the owner doesn't do
       anything you couldn't do by dropping and recreating the conversion. However, a superuser can alter ownership of any conversion anyway.)

PARAMETERS

       name
	   The name (optionally schema-qualified) of an existing conversion.

       new_name
	   The new name of the conversion.

       new_owner
	   The new owner of the conversion.

       new_schema
	   The new schema for the conversion.

EXAMPLES

       To rename the conversion iso_8859_1_to_utf8 to latin1_to_unicode:

	   ALTER CONVERSION iso_8859_1_to_utf8 RENAME TO latin1_to_unicode;

       To change the owner of the conversion iso_8859_1_to_utf8 to joe:

	   ALTER CONVERSION iso_8859_1_to_utf8 OWNER TO joe;

COMPATIBILITY

       There is no ALTER CONVERSION statement in the SQL standard.
