Oh, interesting. I'd seen an actual error on prairiedog, but apparently
some other linkers just silently omit the export, if the symbol is in
a .a file rather than .o.

I proposed in
https://www.postgresql.org/message-id/19581.1538077716@sss.pgh.pa.us
that we should remove pqsignal, as well as
pg_utf_mblen
pg_encoding_to_char
pg_char_to_encoding
pg_valid_server_encoding
pg_valid_server_encoding_id
from libpq's exports, on the grounds that (a) nobody should be using
those (they're undocumented as exports), and (b) anybody who is using
them should get them from libpgport/libpgcommon instead. Thoughts?
