Hi,
I'm still seeing that problem: 9.1 HEAD compiled in my $HOME, with
Debian's 9.0.1-2 libpq5 in /usr/lib:
$ LC_ALL=C bin/psql
psql: connection pointer is NULL
Upgrading to libpq5 9.0.4-1 makes things a bit better:
$ LC_ALL=C bin/psql
psql: invalid connection option "client_encoding"
Setting LD_LIBRARY_PATH fixes it.
Arguably, this is not the "standard" setup, but one that will probably
be quite frequent for someone trying 9.1 in their ~. Shouldn't psql
try to work with older libpq versions by omitting client_encoding?
Setting an RPATH seems like an ugly solution. (I'm not arguing for a
SONAME bump, but this is kind of an ABI change.)
