As far as I remember, this was my proposed change in review a year ago. I think that having a clear analogy between the extension version and the function name would be more clear than sequential numbering of PGSS_V with different extension versions. For pgss 1.4 it was fine to use PGSS_V1_3, because there were no changes in pg_stat_statements_internal. pg_stat_statements 1.3 will call pg_stat_statements_1_3 pg_stat_statements 1.4 - 1.7 will still call pg_stat_statements_1_3. In my opinion, this is the correct naming, since we did not need a new function. but pg_stat_statements 1.8 will call pg_stat_statements_1_4. It's not confusing? Well, no strong opinion. regards, Sergei
