$ ./configure --enable-server --with-postgresql
...

I then install the missing libpq-dev and configure says:
Compiler: gcc
Compiler flags: -g -O2 -I/usr/include/postgresql <= ok
Enable server: yes
Server details:

WEB Monitoring via: no
Native Jabber: no
SNMP: no
IPMI: no
SSH: no
Linker flags: -rdynamic -L/usr/lib <= ok
Libraries: -lm -lrt -lresolv -lpq <= ok

trying with --with-mysql, configure correctly detect missing dev/lib
checking for mysql_config... no
configure: error: MySQL library not found
