Обсуждение: dbsize
Hello *,
I don't know if dbsize a part of the admin business here. I couln't find any
contact infos in the README or the source. I have a 7.3 on solaris 8. When I
try to execute "SELECT database_size('newsdb');" I get the following error
message:
ERROR: MemoryContextAlloc: invalid request size 1684144132
This started to happen when I increased memory sizes in the postgresql.conf.
regards
-andreas

Hm. I cannot see anything wrong with the source code for database_size.
I notice though that it depends on vsnprintf, which is known to be buggy
in some releases of Solaris. Did you use the patch suggested in the
last entry of doc/FAQ_Solaris?

From what, to what?
