Woops. The file that had to be renamed was
/etc/ld.so.conf.d/postgresql-9.0-libs.conf =>
postgresql-9.old-libs.conf . Prior to rename, ldconfig output was:
# ldconfig -p | grep pq
libpqwalreceiver.so (libc6) => /usr/pgsql-9.0/lib/libpqwalreceiver.so
libpqwalreceiver.so (libc6) => /usr/pgsql-9.1/lib/libpqwalreceiver.so
libpq.so.5 (libc6) => /usr/pgsql-9.0/lib/libpq.so.5
libpq.so.5 (libc6) => /usr/pgsql-9.1/lib/libpq.so.5
libpq.so (libc6) => /usr/pgsql-9.0/lib/libpq.so
libpq.so (libc6) => /usr/pgsql-9.1/lib/libpq.so
After the rename:
# cd /etc/ld.so.conf.d
# mv postgresql-9.0-libs.conf postgresql-9.old-libs.conf
# ldconfig
# ldconfig -p | grep pq
libpqwalreceiver.so (libc6) => /usr/pgsql-9.1/lib/libpqwalreceiver.so
libpqwalreceiver.so (libc6) => /usr/pgsql-9.0/lib/libpqwalreceiver.so
libpq.so.5 (libc6) => /usr/pgsql-9.1/lib/libpq.so.5
libpq.so.5 (libc6) => /usr/pgsql-9.0/lib/libpq.so.5
libpq.so (libc6) => /usr/pgsql-9.1/lib/libpq.so
libpq.so (libc6) => /usr/pgsql-9.0/lib/libpq.so
So it appears the problem was inability to connect, although
pg_upgrade reported that it couldn't start the server (I assume
ability to connect is how it determines whether or not the server was
started).
