I don't think that using srand() / rand() in signValue procedure the

Hi!
New revision of patches is attached.
Changes are following:
1) API of generic xlog was changed: now there is no static variables,
GenericXLogStart()
returns palloc'd struct.
2) Generic xlog use elog instead ereport since it reports internal errors
which shouldn't happen normally.

Hello
I did a brief review of bloom contrib and I don't think I like it much.
Here are some issues I believe should be fixed before committing it to
PostgreSQL.
1) Most of the code is not commented. Every procedure should at least
