Include libpq-fe.h instead of postgres/libpq-fe.h.
Also add a macro for checking libpq from Autoconf macro archives.

5# SYNOPSIS
6#
7# AX_LIB_POSTGRESQL([MINIMUM-VERSION])
8#
9# DESCRIPTION
10#
11# This macro provides tests of availability of PostgreSQL 'libpq' library
12# of particular version or newer.
13#
14# AX_LIB_POSTGRESQL macro takes only one argument which is optional. If
15# there is no required version passed, then macro does not run version
16# test.
17#
18# The --with-postgresql option takes one of three possible values:
19#
20# no - do not check for PostgreSQL client library
21#
22# yes - do check for PostgreSQL library in standard locations (pg_config
23# should be in the PATH)
24#
25# path - complete path to pg_config utility, use this option if pg_config
26# can't be found in the PATH
27#
28# This macro calls:
29#
30# AC_SUBST(POSTGRESQL_CPPFLAGS)
31# AC_SUBST(POSTGRESQL_LDFLAGS)
32# AC_SUBST(POSTGRESQL_VERSION)
33#
34# And sets:
35#
36# HAVE_POSTGRESQL
