This macro checks whether 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


after having called AX_CHECK_PGSQL_PRIV_ROOT. You can then do something like the following in your

  @pgclient_root_call@ -f file.sql

If you want the user to set the data, you should support something like these configure options:

          [  --with-pgsql-host=HOST               server is running on HOST @<:@local socket@:>@],
          [pg_host=$withval], [pg_host=])
          [  --with-pgsql-db=DBNAME               use database DBNAME @<:@test@:>@],
          [pg_db=$withval], [pg_db=test])
          [  --with-pgsql-root-user=USER          use user USER, must have root (all) privileges @<:@postgres@:>@],
          [pg_root_user=$withval], [pg_root_user=postgres])
          [  --with-pgsql-password=PASSWORD       use password PASSWORD @<:@none@:>@],
          [pg_password=$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!])])
