After upgrading the TimescaleDB Docker image, every query fails with ERROR: could not access file "$libdir/timescaledb-1.4.0": No such file or directory, even after ALTER EXTENSION timescaledb UPDATE; says the extension is up to date. The extension binary is pinned to the version it was installed with, and the newer image's library set changed. Early images were also just missing the .so files, which was fixed by pulling the rebuilt image.
