I've written a variant of regexp_matches called regexp_matches_positions
which instead of returning matching substrings will return matching
positions. I found use of this when processing OCR scanned text and wanted
to prioritize matches based on their position.

Hi all,
I'd very interesting in taking part in the GSoC with PostgreSQL, as a

Being quite busy at the moment (exam time), I haven't had time to think of
