I've been asked to give a presentation on a recent migration from MMv2 to MMv3
and one of the items in my notes is the question about why Haystack is used for
full-text searching instead of PostgreSQL?
Can someone shed some light on that decision?
The people who developed HyperKitty are no longer actively involved with
Mailman and I can't speak with any authority about their design decisions.
That said, both Django and Mailman core support multiple databases
including PostgreSQL, MariaDB, MySQL, Oracle and SQLite whereas Django's
full text search relies on PostgreSQL specific features and without some
custom implementation, which may not even be possible, would not allow
other DBMs.
Haystack on the other hand provides a unified API that works with
multiple backends. As far as I know, no one has developed a Haystack
backend for PostgreSQL full text search, but as Sam notes in another
reply, there are supported backends for Solr, ElasticSearch, Whoosh and
Xapian.
