Yeah, this is ugly. If you start up psql with the -E switch, you'll see the
queries the psql uses to get the info. Something like this will get what
you want:
select adsrc from pg_class c, pg_attribute, pg_attrdef where
adrelid=c.oid and attrelid=c.oid and attnum=adnum and relname ='employee'
and attname= 'employee_id';
Oh, a hint: if you used the 'serial' type to create the id, the sequence
is named <tablename>_<fieldname>_seq, unless it's to long, then it gets
truncated (fieldname first, then tablename)
