sql: psychopg: investigate how `'infinity'::timestamp` is presented #36116

bobvawter · 2019-03-25T19:55:55Z

Need to cross-check what PG actually sends out on the wire. Looks like the python adapter doesn't like the value it's being asked to reconstitute into the in-memory representation.

ERROR: test_adapt_infinity_tz (psycopg2.tests.test_dates.DatetimeTests)

Hey @mjibson, is this affected by your recent date work? I assume not, since it's timestamps, but just thought I'd ask.

Correct, not related.

The spreadsheet we discussed is unwieldy - hard to edit and impossible to keep up to date. If we write down blacklists in code, then we can use an approach like this to always have an up to date aggregation. So far it seems like there's just a lot of unknowns to categorize still.
