cool!
just a suggestion, can we relax this check? just send a WARNING or a
NOTICE and set "last_block = nblocks - 1"
just an opinion
+ if (PG_ARGISNULL(4))
+ last_block = nblocks - 1;
+ else
+ {
+ last_block = PG_GETARG_INT64(4);
+ if (last_block > nblocks)
+ ereport(ERROR,
+
(errcode(ERRCODE_INVALID_PARAMETER_VALUE),
+ errmsg("ending block number "
INT64_FORMAT " exceeds number of
blocks in relation " INT64_FORMAT, last_block, nblocks)));
+ }
