PG-1674: Fix comment parsing logic at two places (#542)

* PG-1674: Fix query hash calculation comment removal logic

The previous conditions only removed the first few starting characters
of the comment, and leaved everything else there.

This modification fixes this and correctly removes everything.

* PG-1674: Fix performance issues with comment extraction

The previous logic used complex regex parsers, which caused performance
issues with large (megabyte sized) queries. This change removes the
regex dependency and uses the same (fixed) logic from the query hashing
code, which is much faster.

It also checks the related GUC variable, which the previous code
ignored: if we do not want to display extracted comments, we won't
extract them in the first place.

This commit doesn't try to address other issues with comment parsing logic:

* we shouldn't treat comment like things within strings as comments
* we should handle nested C style comments
* we don't extract `--` style comments

All of these issues are still there, as before.

PostgreSQL’s pg_stat_statements provides the basic statistics, which is sometimes not enough. The major shortcoming in pg_stat_statements is that it accumulates all the queries and their statistics and does not provide aggregated statistics nor histogram information. In this case, a user would need to calculate the aggregates, which is quite an expensive operation.",

+# Security Policy
+
+## Supported Versions
+
+pg_stat_monitor project follows rolling release strategy. So all security updates go to new versions.
+
+## Reporting a Vulnerability
+
+Please report any vulnerabilities to our project in [Jira](https://perconadev.atlassian.net/jira/software/c/projects/PG/issues).
+
+If the vulnerability is accepted and confirmed by our experts, you should normally expect us to deliver
+a version with a fix according to the timelines provided below:
+
+For Percona created software (our engineers wrote the code):
+
+- Low/Medium: 120 days
+- High: 90 days
+- Critical: ASAP but should not exceed 30 days
+
+For Non-Percona created software (upstream provided/packaged) from the time the vendor releases a patch:
+
+- Low/Medium: 2nd release from current version
+- High: Next release
+- Critical: Hotfix or no later than next release (our regular release cadence is once every month)
