Quite possible. I managed to compile 7.4 and that error message
disappeared. Anyway, perl dumped core at the very start of the connection.
;) I downgraded DBD::Pg to 1.22 and... it worked! I did not try to upgrade
libpq back to 8.x, but... PHP didn't worked as well with recent version of
libs... After downgrading to 7.4 it worked fine. So there must be
something about libpq anyway.
