I'm using John Lim's ADOdb class to access a PostgreSQL 7.2.4 database. This problem has nothing to do with apache since it happens with the CLI interface too. Reproduce code: --------------- With an empty postgresql installation, I created an empty database, connected to it, created an user and set all privileges on this new database to this user. Connected as the new user on the new database I created some tables. When trying to access this new tables with PHP and ADOdb classes, I got a segmentation fault. At the very end, when running with strace, I got a message before the segmentation fault saying: 'pg_class access denied' When I grant read access on this table to the new user, I got: 'pg_attribute access denied' and so on... When I grant read access to all pg_* tables, the problem disappear and PHP runs ok. Expected result: ---------------- PgSQL Error: Access denied to pg_* system table or something like that. Actual result: -------------- Segmentation Fault if the connection user has no read access on system tables ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25109&edit=1
