From 9a374b77fb53e4cfbca121e4fa278a7d71bde7c4 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 8 Apr 2022 14:55:14 -0400 Subject: Improve frontend error logging style. Get rid of the separate "FATAL" log level, as it was applied so inconsistently as to be meaningless. This mostly involves s/pg_log_fatal/pg_log_error/g. Create a macro pg_fatal() to handle the common use-case of pg_log_error() immediately followed by exit(1). Various modules had already invented either this or equivalent macros; standardize on pg_fatal() and apply it where possible. Invent the ability to add "detail" and "hint" messages to a frontend message, much as we have long had in the backend. Except where rewording was needed to convert existing coding to detail/hint style, I have (mostly) resisted the temptation to change existing message wording. Patch by me. Design and patch reviewed at various stages by Robert Haas, Kyotaro Horiguchi, Peter Eisentraut and Daniel Gustafsson.
