When I tried to apply your patch on HEAD with patch -p1 <
<path_to_patch>, I am getting below errors
(Stripping trailing CRs from patch; use --binary to disable.)
can't find file to patch at input line 17
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
..
I have tried with git am as well, but it failed. I am not sure what
is the reason. Can you please once check at your end? Also, see, if
it applies till 9.5 as I think we should backpatch this.
IIUC, this patch is mainly to get the table name, schema name in case
of the error paths, so that your application can handle errors in case
partition constraint violation, right?
