Dear developers Ogr SQL update capabilities are really impressing but there is one major performance issue with update of many features, exemplified by: ogrinfo -dialect sqlite -sql "UPDATE <table> SET x = 1" PG:”<connection>"
This is painfully slow because ogr updates features one by one and furthermore updates all existing attributes incl. geometries. Eg. updating 10000 features in pgAdmin/psql with UPDATE <table> SET x = 1 executes in milliseconds but takes several minutes with ogr. The current ogr functionality is also not correct from a database transactional point of view. I found an old RFC, https://gdal.org/development/rfc/rfc13_createfeatures.html, requesting this but it was withdrawn for reasons not anymore digitally available.
