This bug uncovered serious issues with how the data was being stored by PSGM.
So it require a complete redesign.
pg_stat_monitor now stores the data locally within the backend process's local
memory. The data is only stored when the query completes. This reduces the
number of lock acquisitions that were previously needed during various stages
of the execution. Also, this avoids data loss in case the current bucket
changes during execution. Also, the unavailability of jumble state during later
stages of executions was causing pg_stat_monitor to save non-normalized query.
This was a major problem as well.
pg_stat_monitor specific memory context is implemented. It is used for saving
data locally. The context memory callback helps us clear the locally saved data
so that we do not store it multiple times in the shared hash.
As part of this major rewrite, pgss reference in function and variable names
is changed to pgsm. Memory footprint for the entries is reduced, data types
are corrected where needed, and we've removed unused variables, functions and
macros.

Removed use of String::Util perl module from TAP test cases, and now using
Text::Trim module instead, as that is more stable. Also removed the
Data::Str2Num perl module as it was not needed any more.
* PG-543: pg_stat_monitor: PostgreSQL's pg_stat_statements compatible view.
The view now carries all the columns as pg_stat_statements. This required fixing
data types of some of the columns, renaming a few, as well inclusion of new
columns to make the view fully compatible with pg_stat_statements.
* PG-543: pg_stat_monitor: PostgreSQL's pg_stat_statements compatible view.
Updating the upgrade sql file from 1.0 to 2.0 version linked with this issue
changes.
* PG-543: pg_stat_monitor: PostgreSQL's pg_stat_statements compatible view.
Updating datum calls to use UInt64 rather than Int64.
As part of this PR, also updated regression test cases that are related to
following JIRA issues as well.
PG-354 pg_stat_monitor: Remove pg_stat_monitor_settings view
Now we not using pg_stat_monitor_settings view, due to this change majority of
TAP testcase requried output changes.
PG-558: Create test case to verify the function names and count in PGSM.
Added additional output file for SQL test case.
PG-554: Remove redundant expected output files from regression.
Removed unnecessary output files in TAP testcases where these were not needed.
In line with pg_stat_statments for PG15, This commit adds eight new cumulative
counters for jit operations, making it easier to diagnose how JIT is used in an
installation. And two new columns, temp_blk_read_time, and temp_blk_write_time,
respectively, show the time spent reading and writing temporary file blocks
on disk.
Moreover, The commit also contains a few indentations and API adjustments.
