Hello,
What is the way to build a binary format (instead of a csv) ? Is there
specification for this file ?

WIN1252 hex value fails, because query parser detect invalid UTF8
sequence (which is logical).
The problem is that I can't find any way to workaround this bug.

Did you mean
SELECT array_agg(id), array_agg(email), parent_id FROM ... GROUP BY

When I run my operator on a GIST node (in the method
gist_range_consistent) it returns NotConsistent / MaybeConsistent /
13 matches
