Hello All,
I am wondering, why I can not add the following ' A 10' in the where
clause i.e. 'where nspname !~* 'pg_' and A 10'
Select nspname, (SELECT count(*) as count FROM pg_tables where schemaname =
nspname) as A
FROM pg_namespace
where nspname !~* 'pg_'
Thanks in advance

The select list can only be computed after the where clause has filtered
the rows, so such a thing would be circular.
