Parameters are not processed by Delphi inside string constants in SQL queries. You are using Dollar-Quoted String Constants (strings delimited by starting and ending with $$). do $$ string constant that is executed as an anonymous code block $$ Ref: PostgreSQL: Documentation: 17: 4.1.

In case you need the final 32-bit version of PostgreSQL to get the correct libraries, here is a link: https://get.enterprisedb.com/postgresql/postgresql-10.23-1-windows.exe

I'm playing along....

I have used DWScript as a scripting system in several products. Used either to provide business rules (no UI, just logic) or as a app/plugin (with UI). The OP language support and performance is excellent. The learning curve is extremely high (no documentation, few examples). Here's an IDE/debugger I wrote for it: DWScriptStudio FWIW, https://www.beginend.net is powered by DWScript.

Another more elaborate example that will show why is compiler strictness for var parameter necessary, and why without it we could easily and unintentionally write the code that can corrupt memory otherwise Pass the Dog, Get the Cat

Perhaps this will help: Magic behind FreeAndNil

It is pretty simple - imagine if the code below would work that way: procedure ReplacePet(var pet: TPet); begin pet.Free; pet := TCat.Create; end; procedure Main; var dog: TDog; begin ReplacePet(dog); dog.Bark; // meow?! end; FreeAndNil is special because it just destroys and assigns nil. But a var parameter does not give that guarantee.
