To whom it may concern,
For performance and security, most of our queries use bind variables. We also implemented auto_explain for tracking down un-optimized queries. Our database supports a large application. During the work-hours, there are 30,000+ queries executed every hour. PostgreSQL logs rotates every hour and each log contains 30,000+ error message like below.
2020-01-27 00:00:03 UTC:xxx.xx.0.189(35556):xxxxxx@xxxxxxdb:[130756]:ERROR: ERROR: 08P01: bind message supplies 0 parameters, but prepared statement "..." requires 1
2020-01-27 00:00:03 UTC:xxx.xx.0.189(35558):xxxxxx@xxxxxxdb:[130756]:LOCATION: exec_bind_message, postgres.c:1601
2020-01-27 00:00:03 UTC:xxx.xx.0.189(35558):xxxxxx@xxxxxxdb:[130756]:STATEMENT: EXPLAIN select ...,...,..,... from ... where ....=$1
These error messages are really overwhelming to us and they are not useful at all. In our opinion, these error messages should not be logged.
