# SYNOPSIS
#
#   AX_PGSQL_PRIV_ROOT(DB, USER, [HOST], [PASSWORD], [ACTION_IF_FAILED], [ACTION_IF_OK])
#
# DESCRIPTION
#
#   This macro checks wether the given PostgreSQL user has root privileges
#   (can create and drop databases) It is recommended to first call
#   AX_CHECK_PGSQL_DB, this makes it easier to locate the cause of error.
#   The macro AX_PROG_PGCLIENT is required by this one.
#
#   The variable $pgclient_root_call is set for later use in Makefiles, if
#   you'd like to make use of this, you must do
#
#     AC_SUBST(pgclient_root_call)
#
#   after having called AX_CHECK_PGSQL_PRIV_ROOT. You can then do something
#   like the following in your Makefile.am:
#
#     @pgclient_root_call@ -f file.sql
#
#   If you want the user to set the data, you should support something like
#   these configure options:
#
#     AC_ARG_WITH(pgsql-host,
#             [  --with-pgsql-host=HOST               server is running on HOST @<:@local socket@:>@],
#             [pg_host=$withval], [pg_host=])
#
#     AC_ARG_WITH(pgsql-db,
#             [  --with-pgsql-db=DBNAME               use database DBNAME @<:@test@:>@],
#             [pg_db=$withval], [pg_db=test])
#
#     AC_ARG_WITH(pgsql-root-user,
#             [  --with-pgsql-root-user=USER          use user USER, must have root (all) privileges @<:@postgres@:>@],
#             [pg_root_user=$withval], [pg_root_user=postgres])
#
#     AC_ARG_WITH(pgsql-password,
#             [  --with-pgsql-password=PASSWORD       use password PASSWORD @<:@none@:>@],
#             [pg_password=$withval], [pg_password=""])
#
#   You can then call the macro like this:
#
#     AX_CHECK_PGSQL_PRIV_ROOT([$pg_db], [$pg_root_user], [$pg_host], [$pg_password], [AC_MSG_ERROR([We need root privileges on database!])])
