Good Engineering Practices while Working Solo

How Much maintenance_work_mem Do I Need?

While I generally like PostgreSQL’s documentation quite a bit, there are some areas where it is not nearly specific enough for users to understand what they need to do. The documentation for maintenance_work_mem is one of those places. It says, and I quote, “Larger settings might improve performance for vacuuming and for restoring database dumps,” but that isn’t really very much help, because if it might improve performance, it also might not improve performance, and you might like to know which is the case before deciding to raise the value, so that you don’t waste memory. TL;DR: Try maintenance_work_mem = 1GB. Read on for more specific advice.

HTTP-over-QUIC will officially become HTTP/3

The protocol that’s been called HTTP-over-QUIC for quite some time has now changed name and will officially become HTTP/3. This was triggered by this original suggestion by Mark Nottingham.

The QUIC Working Group in the IETF works on creating the QUIC transport protocol. QUIC is a TCP replacement done over UDP. Originally, QUIC was started as an effort by Google and then more of a “HTTP/2-encrypted-over-UDP” protocol.
