Fatal error: Call to undefined function: pg_connect()

Hi All,

I updated postgre from 7.2.4 to 7.3.2 in my RHLinux7.3 system and updated
current pghba.conf and postgresql.conf files as per my need. But If I try to
connect through PHP which was connecting earlier with 7.2.4 is giving the
following error

Fatal error: Call to undefined function: pg_connect()

Can any body encounter the same problem earlier can help me that in solving.

Thanks alot,
