This replaces dblink's blocking libpq calls, allowing cancellation and allowing DROP DATABASE (of a database not involved in the query). Apart from explicit dblink_cancel_query() calls, dblink still doesn't cancel the remote side. The replacement for the blocking calls consists of new, general-purpose query execution wrappers in the libpqsrv facility. Out-of-tree extensions should adopt these. The original commit d3c5f37dd543498cc7c678815d3921823beec9e9 did not back-patch. Back-patch now to v16-v13, bringing coverage to all supported versions. This back-patch omits the orignal's refactoring in postgres_fdw. Discussion: https://postgr.es/m/20231122012945.74@rfd.leadboat.com
