I do this all the time; In fact, I've written a dynamic aggregate engine
that uses a sudo bind variable technique & dynamic joins with dependency
injection because the table names and query logic are not known at run
time - all in plpgsql.

Hey,
We have a search method that depending on search params will join 3-5
tables, craft the joins and where section. Only problem is, this is
done in rather horrible java code. So using pgtap for tests is not
feasible.
I want to move the database complexity back to database, almost
writing the query construction in the plpgsql or python as stores
procedure, any suggestions ?
Unfortunately PostgreSQL won't eliminate unnecessary joins from a
view, so I can't just create one view and simple code adding where's,
order by, etc.
No, I don't want to use orm.
It's a matter of taste. Pretty much every PL has facilities for
constructing and running dynamic sql. PLPgsql ,PLPerl, PLV8 ...
cheers
