Historically, hba.c limited tokens in the authentication configuration files (pg_hba.conf and pg_ident.conf) to less than 256 bytes. We have seen a few reports of this limit causing problems; notably, for moderately-complex LDAP configurations. Let's get rid of the fixed limit by using a StringInfo instead of a fixed-size buffer. This actually takes less code than before, since we can get rid of a nontrivial error recovery stanza. It's doubtless a hair slower, but parsing the content of the HBA files should in no way be performance-critical. Although this is a pretty straightforward patch, it doesn't seem worth the risk to back-patch given the small number of complaints to date. In released branches, we'll just raise MAX_TOKEN to ameliorate the problem. Discussion: https://postgr.es/m/1588937.1690221208@sss.pgh.pa.us
