39896cb955 Fixed CORE-1671: atexit() calls in client libraries cause segfaults 
and CORE-1079: Every attach of fbclient/fbembed library leaks 64KB of memory

- applied it to global objects.

Also some related cleanup.

b15c8531e0 Change my FB1 logic that returned the table's owner for the role when a not null field with default CURRENT_ROLE is added, the table has records already and the user does a SELECT. Now, if CURRENT_USER==table's owner, then the CURRENT_ROLE is returned, otherwise NONE. 2004-11-28 08:25:09 +00:00
