Обсуждение: replicating tsearch2 across versions of postgres
I am getting the following error(s) when replicating tsearch2 from v 7.4.x to v 8.1.0
remoteWorkerThread_1: copy from stdin on local node - PGRES_FATAL_ERROR ERROR: function "spell_init(text)" does not exist@4000000043a9708d21558414 CONTEXT: COPY pg_ts_dict, line 1, column dict_init: "spell_init(text)"
the problem is that the function signatures have changed
spell_init(text) is now spell_init(internal) so the function can't be found on the destination node.
My solution is to not replicate the internal tsearch2 tables. Is this going to be problematic ?
Is it possible to add the old signatures back for backward compatibility ? Something like a tsearch2-compat lib ?

The old signatures were security holes. We are not going to put them
back. I would suggest changing the functions on the 7.4 machine to the
new signatures --- see the 7.4.8 release notes.

Thanks, that might be easier than first thought.

Is it possible to just not replicate the internal tsearch tables ?
