problem with dibi::getConnection()->getDatabaseInfo()->getTables() on empty db (postgre driver)

[Edke]

There is a problem getting array of tables if database is empty while using postgre driver.

Problem is in postgre.php in GetTables(). If there are no rows in resultSet, pg_fetch_all() returns FALSE . And this cause problems in DibiDatabaseInfo.php in init() method on line 115. Foreach expects it to be array instead and it throws warning 'Invalid argument supplied for foreach()'.

fix:

diff --git a/libs/dibi/drivers/postgre.php b/libs/dibi/drivers/postgre.php
