I'm strongly on this side emotionally, but also I'm on Tom and Andres's side that exposing querid that way is not the right thing. Doing that means we don't need exact correspondence between top-level query and queryId (in nested or multistatement queries) in this patch. pg_stat_statements will allow us to do the same thing by having additional uint64[MaxBackends] array in pgssSharedState, instead of expanding PgBackendStatus array in core by the same size. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
