You didn't attach the patch, but in any case, I would be astonished if there is no work required beyond creating the matching array type. The reverse case (domains over arrays) has half a dozen special cases required to make it work smoothly. Probably the considerations on this side are totally different, but it's hard to believe there aren't any. One case that seems likely to be pretty squishy is an array of a domain over an array type. One would wish to be able to do foo to extract an element of the contained array. That won't work as-is because the notation will be taken as a multi-dimensional subscript, but I would expect that (foo) should work. Does it? Does ruleutils.c always include the necessary parens when reverse-listing such a construct? Is it possible to assign to such a sub-element, and if so, do the domain constraints get checked properly? Domain over an array that is of a domain type might be another fun case. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
