Subject: [PATCH v2] Suppress length of Notice/Error in PQtrace regress mode
Date: Fri, 2 Apr 2021 10:51:42 -0300
A (relatively minor) annoyance of ErrorResponse/NoticeResponse messages
as printed by PQtrace() is that their length might vary when we move
error messages from one file to another, one function to another, or
even when their location line number changes number of digits.
To avoid having to adjust expected files for some tests, make the
regress mode of PQtrace() suppress the length word of those messages.
