Hellos,

How to manually increase pg_multixact members and offsets?

Does a transaction waiting for exclusive lock or shared lock result into entry being created in pg_multixact?

Excerpt of multixact.c:
/*-------------------------------------------------------------------------
2  *
3  * multixact.c
4  * PostgreSQL multi-transaction-log manager
5  *
6  * The pg_multixact manager is a pg_clog-like manager that stores an array of
7  * MultiXactMember for each MultiXactId. It is a fundamental part of the
8  * shared-row-lock implementation.

Regards...
