From fe415ff10408a1487d5773b47459306476ec58f0 Mon Sep 17 00:00:00 2001 From: Tomas Vondra Date: Thu, 30 May 2019 16:16:12 +0200 Subject: [PATCH] Make error logging in extended statistics more consistent Most errors reported in extended statistics are internal issues, and so should use elog(). The MCV list code was already following this rule, but the functional dependencies and ndistinct coefficients were using a mix of elog() and ereport(). Fix this by changing most places to elog(), with the exception of input functions. This is a mostly cosmetic change, it makes the life a little bit easier for translators, as elog() messages are not translated. So backpatch to PostgreSQL 10, where extended statistics were introduced.
