Glad to see all the new regex functions. I recently moved a database from AWS Redshift to Postgres on Heroku and was shocked to see how many functions like regexp_substr() weren't available. Wish this had come sooner so I didn't have to rewrite so many of my queries.
That’s an interesting change from a analytical to transactional postgres flavour. What workload is on this DB?
The app is so small that we didn't need a separate database copy just for reporting.
