Reducing the log spam

Inspired by feedback to [1], I thought about how to reduce log spam.

My experience from the field is that a lot of log spam looks like

  database/table/... "xy" does not exist
  duplicate key value violates unique constraint "xy"

So what about a parameter "log_suppress_sqlstates" that suppresses
logging ERROR and FATAL messages with the enumerated SQL states?

My idea for a default setting would be something like

  log_suppress_sqlstates = '23505,3D000,3F000,42601,42704,42883,42P01'

but that's of course bikeshedding territory.

Yours,
Laurenz Albe
