Hello,
I understand that when the pg_stat_statements.save=true the
statement statistics are saved at global/pg_stat_statements.stat. This file
is read on next startup and then deleted.
If there is a crash i understand that pg_stat_statements.stat file is not
created even if pg_stat_statements.save=true.
If the crash happened before pg_stat_statements.stat file is deleted
then, on recovery, is that pg_stat_statements.stat file deleted?
On crash recovery, are statement statistics reset ,to same values as would
be the case on normal startup in the case pg_stat_statements.save=false?
Thank you
Sameer
