ax_check_pgsql_db

Synopsis

AX_CHECK_PGSQL_DB([DB], [USER], [HOST], [PASSWORD], [ACTION_IF_FAILED], [ACTION_IF_OK])

Description

This macro checks whether we can connect to a PostgreSQL server with the given data. The macro AX_PROG_PGCLIENT is required by this one. The variable $pgclient_call is set for later use in Makefiles, if you’d like to make use of this, you must do

  AC_SUBST(pgclient_call)

after having called AX_CHECK_PGSQL_DB. You can then do something like the following in your Makefile.am:

  @pgclient_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=DATABASE             use DATABASE @<:@tarantoola@:>@],
          [pg_db=$withval], [pg_db=tarantoola])

  AC_ARG_WITH(pgsql-user,
          [  --with-pgsql-user=USER               use USER @<:@postgres@:>@],
          [pg_user=$withval], [pg_user=postgres])

  AC_ARG_WITH(pgsql-password,
          [  --with-pgsql-password=PASSWORD       use PASSWORD @<:@none@:>@],
          [pg_password=$withval], [pg_password=""])

You can then call the macro like this:

  AX_CHECK_PGSQL_DB([$pg_db], [$pg_user], [$pg_host], [$pg_password], [AC_MSG_ERROR([We need a database connection!])])
