Tom Lane cb37c29106 Fix index matching for operators with mixed collatable/noncollatable inputs. ... If an indexable operator for a non-collatable indexed datatype has a collatable right-hand input type, any OpExpr for it will be marked with a nonzero inputcollid (since having one collatable input is sufficient to make that happen). However, an index on a non-collatable column certainly doesn't have any collation. This caused us to fail to match such operators to their indexes, because indxpath.c required an exact match of index collation and clause collation. It seems correct to allow a match when the index is collation-less regardless of the clause's inputcollid: an operator with both noncollatable and collatable inputs could perhaps depend on the collation of the collatable input, but it could hardly expect the index for the noncollatable input to have that same collation. Per bug #6232 from Pierre Ducroquet. His example is specifically about "hstore ? text" but the problem seems quite generic.		2011-09-29 00:43:42 -04:00
