that'slarge enough to stop worrying about it.
Hm. I'm wondering why I'm getting out of memory errors now with just
25k lines in pg_hba.conf. It looks like the HbaLine struct is "only"
472 bytes so the list should only be occupying about 11MB. In fact
it's occupying about a gigabyte:
TopMemoryContext: 8192 total in 1 blocks; 5264 free (1 chunks); 2928 used ident parser context: 0 total in 0 blocks; 0
free(0 chunks); 0 used hba parser context: 956300288 total in 126 blocks; 1694136 free (82
chunks); 954606152 used
The lines in my pg_hba.conf don't have any databases or roles listed
so there shouldn't be any tokens taking up space either. I just copied
this line 25,000 times:
local all all trust
