Fix regex for $$ PostgresSQL string in convert placeholder

* Correct wrong comment lookup
* simplify regex by excluding comment and string blocks before
* simpler lookup for each type
* update checks for more tests for various special cases

In DB IO
* add a function to return all placeholders found in a query
* only numbered parameters are looked up
