Hi Pavel,

>> I am sending an enhanced patch about the regress test for plpgsql's debug API.

Thanks for the test! I noticed some little issues with formatting and typos. The corrected patch is attached.

You probably already noticed, but for the record - AppVeyor doesn't seem to be happy still [1]:

```

src/test/modules/test_dbgapi/test_dbgapi.c(17): fatal error C1083: Cannot open include file: 'plpgsql.h': No such file or directory [C:\projects\postgresql\test_dbgapi.vcxproj]

```
