I'm interested to use Pglite for local unit-testing, but I'm using timescaledb in prod, do you think you will have this extension pre-built for Pglite?
I'm not aware of anything trying to compile timescale for it. Some extensions are easer than other, if there is limited (or ideally no) network IO and its written in C (Timescale is!) with minimal dependencies then its a little easer to get them working.
I’ve had incredible success with testcontainers for local unit-testing
We have a walk-through on porting extensions to PGlite: https://pglite.dev/extensions/development#building-postgres-...
