<p>Carlo,</p>
<p>you're conflating two different things:</p>
<p>- PostgreSQL & PostGIS version support in GDAL. It might
still semi work for you with dropped supported version by
chance/accident.</p>
<p>- PostgreSQL & PostGIS version support in QGIS PostgreSQL
provider. Looking quickly at git log, I don't see anything
explicit abut dropping them. I suppose that support for those
older versions broke by accident or wasn't explicitly mentionned. </p>
<p>In any case those ancient versions aren't supported, have likely
unfixed security issues, and it would be hard for us to test
against them.</p>
<p>So use older QGIS versions if you really need to stick with your
ancient PostgreSQL & PostGIS version. There's hardly no chance
you can convince us (at least me for the code I'm responsible of)
to bring back support for them</p>
<p>Even</p>
