4 # SYNOPSIS
5 #
6 # AX_LIB_POSTGRESQL([MINIMUM-VERSION])
7 #
8 # DESCRIPTION
9 #
10 # This macro provides tests of availability of PostgreSQL 'libpq'
11 # library of particular version or newer.
12 #
13 # AX_LIB_POSTGRESQL macro takes only one argument which is optional.
14 # If there is no required version passed, then macro does not run
15 # version test.
16 #
17 # The --with-postgresql option takes one of three possible values:
18 #
19 # no - do not check for PostgreSQL client library
20 #
21 # yes - do check for PostgreSQL library in standard locations
22 # (pg_config should be in the PATH)
23 #
24 # path - complete path to pg_config utility, use this option if
25 # pg_config can't be found in the PATH
26 #
27 # This macro calls:
28 #
29 # AC_SUBST([POSTGRESQL_CFLAGS])
30 # AC_SUBST([POSTGRESQL_CPPFLAGS])
31 # AC_SUBST([POSTGRESQL_LDFLAGS])
32 # AC_SUBST([POSTGRESQL_VERSION])
33 #
34 # And sets:
35 #
36 # HAVE_POSTGRESQL
37 #
38 # LAST MODIFICATION
39 #
40 # 2006-07-16
41 # 2010-05-14 MKS: Added POSTGRESQL_CPPFLAGS
42 # 2011-06-21 AJB: Added workaround for Fedora pg_config oddity
43 # 2011-08-01 MKS: Changed PG_CONFIG to POSTGRESQL_CONFIG
44 # Made test constructs more portable
