cannot use CTEs in core query

with update_some_other_foo as(
  insert into rep_table values(10,1) returning x
)
update rep_table
set y = 10
from update_some_other_foo
where rep_table.x = update_some_other_foo.x;
ERROR:  relation "(null)" is not managed by pg_paxos

Thanks for reporting this issue, it is the same one as #4. It is now fixed in the master branch.

In the develop branch this particular query is broken because it deparses the transformed query plan to do parameter substitution, but the deparsing functions (copied from ruleutils.c in PostgreSQL) seems to add an invalid prefix so "returning x" becomes "returning rep_table_1.x", which errors out.
