Move checking for unscannable matviews into ExecOpenScanRelation, which is a better place for it first because the open relation is already available (saving a relcache lookup cycle), and second because this eliminates the problem of telling the difference between rangetable entries that will or will not be scanned by the query. In particular we can get rid of the not-terribly-well-thought-out-or-implemented isResultRel field that the initial matviews patch added to RangeTblEntry. Also get rid of entirely unnecessary scannability check in the rewriter, and a bogus decision about whether RefreshMatViewStmt requires a parse-time snapshot. catversion bump due to removal of a RangeTblEntry field, which changes stored rules. |
