ALTER CONVERSION - change the definition of a conversion
ALTER CONVERSION name RENAME TO newname ALTER CONVERSION name OWNER TO newowner
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 conversions schema. (These restrictions enforce that altering the owner doesnt do anything you couldnt do by dropping and recreating the conversion. However, a superuser can alter ownership of any conversion anyway.)
name The name (optionally schema-qualified) of an existing conversion. newname The new name of the conversion. newowner The new owner of the conversion.
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;
There is no ALTER CONVERSION statement in the SQL standard.
CREATE CONVERSION [create_conversion(7)], DROP CONVERSION [drop_conversion(l)]
