RHEL 3 and RHEL 4 PHP RPMs are compiled with libpq.so.3 . However, beginning from 8.0.2, libpq was bumped to version 4. So this broke compatibility between the packages from PostgreSQL.org and RHEL PHP. In order to solve that problem, we built a compatibility RPM which installs libpq.so.3 and other libs to your system: # rpm -ql compat-postgresql-libs /usr/lib64/libecpg.so.4 /usr/lib64/libecpg.so.4.1 /usr/lib64/libecpg_compat.so.1 /usr/lib64/libecpg_compat.so.1.2 /usr/lib64/libpgtypes.so.1 /usr/lib64/libpgtypes.so.1.2 /usr/lib64/libpq.so.3 /usr/lib64/libpq.so.3.1 If you use Red Hat's RPMs, you don't have this problem because they provide PostgreSQL 7.4, which satisfies PHP dependency. Here is a sample output from my RHEL 4 (x86_64) home box: # rpm -e compat-postgresql-libs error: Failed dependencies: libpq.so.3()(64bit) is needed by (installed) dovecot-0.99.11-2.EL4.1.x86_64 libpq.so.3()(64bit) is needed by (installed) perl-DBD- Pg-1.31-6.x86_64 libpq.so.3()(64bit) is needed by (installed) php- pgsql-4.3.9-3.9.x86_64 We could not document that well except questions in mailing lists and my PostgreSQL blog, that's my mistake I believe.
