quoting problem

Hi there,

I'm a bit confused with the quoting, see below:

contrib_regression=# ALTER OPERATOR CLASS pg_catalog.int4_ops USING btree OWNER TO megera;
contrib_regression=# ALTER OPERATOR CLASS "pg_catalog.int4_ops" USING btree OWNER TO megera;
ERROR:  operator class "pg_catalog.int4_ops" does not exist for access method "btree"
contrib_regression=# ALTER OPERATOR CLASS pg_catalog."int4_ops" USING btree OWNER TO megera;
ALTER OPERATOR CLASS

Is't intentional or bug ?
    Regards,        Oleg

It's normal. In your second example you've got a single identifier. The
identifier itself does not contain the '.', that's a seperator and so
isn't part of the actual identifier.

Have a nice day,
