Hi all,
This patch allows ALTER TABLE/DROP CONSTRAINT to drop UNIQUE constraints by
dropping the relevant index.
This is a prelim patch that I need comment on (The @@ comments), and I've
edited some things out by hand, so I don't recommend applying it to anything
just yet.
I have added an IsIndex function to indexcmds.c and a RemoveUniqueConstraint
to heap.c, plus modified command.c's AlterTableDropConstraint function to
call RemoveUniqueConstraint.
Note that I have disabled inheritance support for unique constraints - since
it's impossible to have two indices of the same name anyway...
Comments please.
Chris
