engine from the stream when the chunk size is reached.

Bug
---
Inspection triggered only in the specified chunk sizes may be too late

could result in delayed inspection, incorrect data logged with a transaction
and logs misindicating the pkt that triggered an alert.

Fix
---
Fix this by making an explicit call from all respective applayer parsers to
trigger raw stream inspection which shall make the data available for inspection
in the following call of the stream engine. This needs to happen per direction

Juliana Fajardini [Tue, 20 May 2025 15:59:10 +0000 (12:59 -0300)] 
pgsql: debug validation on duplicated request msgs

There shouldn't be duplicated messages in the requests Vec. And thus
the parser shouldn't log duplicated keys nor messages. Add debug
validations to ensure this.

With PGSQL's current state machine, most frontend/ client messages will
lead to the creation of a new transaction - which would prevent
duplicated messages being pushed to the requests array and reaching the
logger.

The current exceptions for that are:

- CopyDataIn
- CopyDone
- CopyFail

Thus, debug statements were added for those cases.

CopyDone and CopyFail, per the documentation, shouldn't be seen
duplicated on the wire for the same transaction. CopyDataIn -- yes, but
we consolidate those, so the expectation is that they won't be
duplicated in the requests array or when reaching the logger either.
