That's doing what it's supposed to. Compare
regression=# select 'Moo'::regclass;
ERROR: relation "moo" does not exist
LINE 1: select 'Moo'::regclass;
^
regression=# select '"Moo"'::regclass;
ERROR: relation "Moo" does not exist
LINE 1: select '"Moo"'::regclass;
^
The regclass input converter applies the same case-folding rules as
the SQL parser does, ie, fold unless double-quoted.
Ahh, duh. Hrm... I ran across this because someone here got confused by this:
SELECT pg_total_relation_size( schema_name || '.' || relname ) FROM
pg_stat_all_tables
ERROR: relation "moo" does not exist
Obviously the problem is that they needed to use quote_ident(), but I was
hoping to make the error less confusing to deal with.
Perhaps we can add a hint? Something to the effect of "Do you need to use
double-quotes or quote_ident()?"
