Bug reference: 14292

PostgreSQL version: 9.3.14
Operating system: RHEL7
Description:

While configuring postgresql 9.3 we received below errors.
**********************************
configure: error: readline library not
found
If you have readline already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper
directory.
Use --without-readline to disable readline support
***********************************
configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper
directory.
Use --without-zlib to disable zlib support.
***********************************
So we had to use below configuration command.
*************************************
./configure --mandir=/u01/Database/PostgreSQL/9.3/man
--prefix=/u01/Database/PostgreSQL/9.3 --without-readline --without-zlib
**************************************
But I believe there would be some issue in the future if we disable zlib. So
could you please if we can reconfigure the postgresql with zlib with out
disturbing the existing system or should be reinstall the database?

Please let us know.
