You can use this:
- define in your postgresql.conf:
custom_variable_classes = 'myvar'
- use within psql:
test=# set myvar.benutzer = 'foo';
SET
test=*# select * from foo;
id | name
----+------
1 | foo
2 | bar
(2 rows)
test=*# select * from foo where name=current_setting('myvar.benutzer');
id | name
----+------
1 | foo
(1 row)
test=*# set myvar.benutzer = 'none';
SET
test=*# select * from foo where name=current_setting('myvar.benutzer');
id | name
----+------
(0 rows)
