different results in matrix inversion on newer debian
@jot_ha reported:
Problem: The nfiestahtc installcheck is fine, all 5 tests passed with ok.
But when running installcheck-all, fn_inverse fails. I attached the files regression.out and regression.diffs.
For comparison I've run the whole setup with the nfiesta_pg provision script from the repo (with adjustements to Postgres 16 and my username) (see attachments). But this results in the exact same error.
First diff looks like an issue of rounding. The two other diffs I do not yet understand.
Maybe it is something that you're familiar with and you can point me into some direction.
