CREATE SYNONYM ...

this patch implements CREATE SYNONYM

syntax:

CREATE SYNONYM [TABLE | INDEX | SEQUENCE | VIEW] synname ON orgname;

CREATE SYNONYM FUNCTION synname ON funcname(arg, arg, ...);

DROP SYNONYM [TABLE | INDEX | SEQUENCE | VIEW] synname;

DROP SYNONYM FUNCTION synname(arg, arg, ...);

for details about synonyms see pg_synonym table.
The synonym is just like a unix hardlink.
Every user who has CREATE rights can create a synonym.

This feature is especially important to people who want to port from
Oracle to PostgreSQL (almost every customer who ports larger Oracle
applications will asked for it).

Documentation will be submitted this week.
The patch applies without error against 8.1.3.

Many thanks and best regards,

Hans
