RE: pg_hba.conf "authentication file token too long, skipping"

" A one-line improvement would be to increase that constant, but it doesn't look very much harder to get rid of that
fixed-sizebuffer altogether in favor of a StringInfo." 

Is this something that can be included in the next patch?

Yeah, your ldapsearchfilter option is hitting the 256-byte MAX_TOKEN limit in hba.c.  A one-line improvement would be
toincrease that constant, but it doesn't look very much harder to get rid of that fixed-size buffer altogether in favor
ofa StringInfo.
