Hi all,
I working in a patch to include support of "IF NOT EXISTS" into "CREATE"
statements that not have it yet.
I started with "DefineStmt" section from "src/backend/parser/gram.y":
- CREATE AGGREGATE [ IF NOT EXISTS ] ...
- CREATE OPERATOR [ IF NOT EXISTS ] ...
- CREATE TYPE [ IF NOT EXISTS ] ... [AS [{ENUM | RANGE}] (...)]
- CREATE TEXT SEARCH {PARSER | DITIONARY | TEMPLATE | CONFIGURATION} [ IF
NOT EXISTS ] ...
- CREATE COLLATION [ IF NOT EXISTS ] ...
My intention is cover anothers CREATE statements too, not just the above.
If has no objection about this implementation I'll finish him and soon I
sent the patch.
Regards,
