Tom Lane	11f7b29054	Allow ORDER BY, LIMIT in sub-selects. Fix most (not all) cases where ... the grammar did not allow redundant parentheses around sub-selects. Distinguish LIMIT ALL from LIMIT 0; make the latter behave as one would expect.	2000-11-05 00:15:54 +00:00
Tom Lane	2f35b4efdb	Re-implement LIMIT/OFFSET as a plan node type, instead of a hack in ... ExecutorRun. This allows LIMIT to work in a view. Also, LIMIT in a cursor declaration will behave in a reasonable fashion, whereas before it was overridden by the FETCH count.	2000-10-26 21:38:24 +00:00
