Why are you comparing PostgreSQL to an in-memory SQLite instead of a file-based one? Wow, memory is faster than disk, who would have thought?

Because it doesn't make a difference, because `SELECT 1` doesn't need to touch the database:

Why are you doing meaningless microbenchmarks?
Are you claiming that this does not show the speed difference between socket vs in process communication?

I hope you understand that your claim boils down to stating that SQLite is faster at doing nothing at all, which is a silly case to make.
The original claim being discussed is about the overhead of an in-process database vs. a database server in a separate process, not about whether SQLite or PostgreSQL have a faster database engine.
How about pg on Unix socket?
