Re: is a user in a group?

Hi,

You need create a function use PLPGSQL(or PL/Perl) say:

ismember(groupname,username) return bool

since select grolist from pg_group where proname=groupname will return
you an array,
you can use a loop compare each element with the id from usesysid from
pg_user which match username.
