[QGIS-Developer] Reduced compatibility with old PosgreSQL/PostGIS databases in v. 4.0.0

[Carlo A. Bertelli (Charta s.r.l.)]

I understand that GDAL declares

> Starting with GDAL 3.9, only PostgreSQL >= 9 and PostGIS >= 2 are
> supported.

but version 3.44 still can open layers from a v. 8.4 database and PostGIS
1.5.
Now version 4 does not open layers from this database.
GDAL v. 3.12.3 per se can open these layers, ogrinfo works well, ogr2ogr
lets me upload data from files to the same database.
What happened with the new version? I cannot even change parameters per
table. Is there a solution for this?
Unfortunately I cannot change the database nor upgrade it, even if I would
like very much.
