Thanks. This looks good. I'm attaching what I intend to push, which just
adds a log message and some cosmetic changes compared to your version. Here
are the missing symbols restored by the patch:

pg_encoding_to_char
pg_utf_mblen
pg_char_to_encoding
pg_valid_server_encoding
pg_valid_server_encoding_id

I was ambivalent about whether to back-patch to v13 or to stop at v14, but I
decided that v13 should have this change. We should expect sad users when
libpq lacks a documented symbol. Complaints about loss of undocumented
symbols (e.g. pqParseInput3) are unlikely, and we're even less likely to have
users opposing reintroduction of long-documented symbols. An alternative
would be to have v13 merge the symbol lists, like your original proposal, so
we're not removing even undocumented symbols. I doubt applications have
accrued dependencies on libpq-internal symbols in the year since v13 appeared,
particularly since those symbols are inaccessible on Linux. Our AIX export
lists never included libpgport or libpgcommon symbols.
