Alex Shapalov launches PGX, an open-source Rust Postgres runtime for AI agents

Alex Shapalov announces PGX, an open-source Postgres runtime written in Rust for AI agents, and says it runs thousands of Postgres databases in one process.

In his launch post on X he says 1,000 idle databases use 659 MB of RAM, an idle database uses about 0.7 MB, and a 674 MB database clones in 85 ms. These figures are his own claims and no independent benchmark is reported.
