./configure --prefix=/usr/local/pgsql

.....

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.

解决方法

apt-getinstallzlib1g-dev

或

apt-cachesearchzlibdev
