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

+# SYNOPSIS
+#
+# AX_LIB_POSTGRESQL([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+# This macro provides tests of availability of PostgreSQL 'libpq' library
+# of particular version or newer.
+#
+# AX_LIB_POSTGRESQL macro takes only one argument which is optional. If
+# there is no required version passed, then macro does not run version
+# test.
+#
+# The --with-postgresql option takes one of three possible values:
+#
+# no - do not check for PostgreSQL client library
+#
+# yes - do check for PostgreSQL library in standard locations (pg_config
+# should be in the PATH)
+#
+# path - complete path to pg_config utility, use this option if pg_config
+# can't be found in the PATH
+#
+# This macro calls:
+#
+# AC_SUBST(POSTGRESQL_CPPFLAGS)
+# AC_SUBST(POSTGRESQL_LDFLAGS)
+# AC_SUBST(POSTGRESQL_VERSION)
+#
+# And sets:
+#
+# HAVE_POSTGRESQL
