While looking into 0002, I noticed some minor ereport calling style
issues.
Recently we start to use the style:
ereport(ERROR,
errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
Rather than (old style):
ereport(ERROR,
(errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
Grepping patches shows following results that hire the old style.
$ grep -n '(errcode' *|grep '+'
