PG-453: Normalize query does not work with INSERT statements.
The commit fixes the issue similar to pg_stat_statements. Jumble query skips in
case of INSERT statements to avoid the duplicate queryid, but in another
commit we already solved that problem with another way.
The buckets are now created with the start time a modulus of the bucket time size.
So if we have a 10 second bucket, the start times would reflect that:
- Bucket1: 00:00:00
- Bucket2: 00:00:10
- Bucket3: 00:00:20
...
Previously, the start time of the bucket was aligned with the first query that
arrives in that bucket. However, now the behaviour is changed. So, even if the
first query for bucket 2 arrives at 00:00:13, the start time would still be set
to 00:00:10.
This change now makes the bucketing separated out by fixed time windows so that
external applications can easily consume that data and chart it.
Also, as part of this change, locking of pgss is updated now and extended
to last the bucket related changes.
pg_stat_monitor.pgsm_normalized_query needs to be 0 by default because
people will get Query examples. This is one of the main user-faced
advantages of pgsm over pgss (pg_stat_statements).

While analyzing the pg_stat_monitor installation scripts I found several
vulnerabilities. pg_stat_monitor uses CREATE OR REPLACE to install its
functions which is a security hazard. An attacker can precreate the functions
have a superuser install the extension and after installation the attacker
can switch out the function with a malicious version since he would still
be the owner of the function. Instead of CREATE OR REPLACE the installation
script should use plain CREATE to prevent this attack.
