So it seems to me, that exec is called in the wrong spot.
But the whole thing works for sqlite and MySql/Mariadb, so I'm assuming
the problem is likely in postgres specifics of qsql. Also - it looks
like the same function (deleteKeyValuePaird) is called with identicaly
parameters more than once, on only one of those fails. I'll read
through the debugging hints you provided before I decide how to proceed.
To track this down (After all F1 identifies 241 iterations) I would
derive a new result object from QPSQLResult or QSqlResult and
override prepare() and exec() to keep track of the calls and their
return code. Then use this object to add specific debugging
code/output.
I think the only reason that number is so high is that I made a whole
lot of attempts within that ddd/gdb session. I just started a new
session, and the first iteration I saw was _A, so I might try putting a
watch on that value, if it is something gdb can do.
