Another approach to solve my problem would be a function that receives a dynamic SQL, runs it and returns a XML or JSON and on client side I convert that XML back to a recordset. Is that possible ?
Yes, you can pass "text" SQL into a pl/pgsql function and "EXECUTE" it. That text must be plain SQL though, not pl/pgsql.
Converting pl/pgsql into plain SQL and executing it as a CTE seems like an over-solution. What should be reasonably possible to rewrite the "execute block" as a "create function" then modify your clients to do send "select * from function();" instead of "execute block ..."
If I was you I'd even be curious enough to see if maybe there is an external third-party extension "pl/firebase" language out there which would let you comfortably copy-paste the block text into the function body with minimal or no editing.

p.s. reading PostGres is hard on our (mine at least) eyes. Its either Postgres, or PostgreSQL - neither with a capital G.
