PostgreSQL 12 many regression failures rounding and extra warning output

[robe]

I'm not sure how long this has been going on. I suspect somewhere between Feb 11th and Feb 15th is when it started.

Debbie has this with pg12 head I've disabled her 12 testing on PostGIS 2.5, but kept it on for 3.0

All look like rounding except for the estimatedextent. I can't tell if it's in 12 whatever we have is running 4 times instead of once or just some artifact of the WARNING system in 12 that it outputs the warning 4 times.

I compiled PostgreSQL 12 and get same failures.

at a glance looks like mostly rounding issues that perhaps buttoning up the tests with some grace for floats will solve.
