Don't consider a constant of regconfig or other reg* types to be shippable unless it refers to a built-in object, or an object in an extension that's been marked shippable. Without this restriction, we're too likely to send a constant that will fail to parse on the remote server. For the regconfig type only, consider OIDs up to 16383 to be "built in", rather than the normal cutoff of 9999. Otherwise the initdb-created text search configurations will be considered unshippable, which is unlikely to make anyone happy. It's possible that this new restriction will de-optimize queries that were working satisfactorily before. Users can restore any lost performance by making sure that objects that can be expected to exist on the remote side are in shippable extensions. However, that's not a change that people are likely to be happy about having to make after a minor-release update. Between that consideration and the lack of field complaints, let's just change this in HEAD. Noted while fixing bug #17483, although this is not precisely the problem that that report complained about. Discussion: https://postgr.es/m/1423433.1652722406@sss.pgh.pa.us |
