Tom Lane e1fd61c8ce Ensure casting to typmod -1 generates a RelabelType. ... Fix the code changed by commit 5c056b0c2 so that we always generate RelabelType, not something else, for a cast to unspecified typmod. Otherwise planner optimizations might not happen. It appears we missed this point because the previous experiments were done on type numeric: the parser undesirably generates a call on the numeric() length-coercion function, but then numeric_support() optimizes that down to a RelabelType, so that everything seems fine. It misbehaves for types that have a non-optimized length coercion function, such as bpchar. Per report from John Naylor. Back-patch to all supported branches, as the previous patch eventually was. Unfortunately, that no longer includes 9.6 ... we really shouldn't put this type of change into a nearly-EOL branch.
