Hi,
The speed problem disappeared. This new version
runs that test in 2.8 seconds instead of 9. Yay!
So it's now faster than with v4.2.2 (i.e. 4 seconds).
Adding in a call to pgdb.set_typecast('anyarray', lambda v, c: v)
makes it behave like v4.2.2 and taking roughly the same
time (3.5 seconds) as the original (was 4s, today it's 3.3s).
So that looks great. Thanks.
cheers,
raf
