Hmm, well there's *something* mighty curious about the history of this table. The xmin values span a range of almost 400,000 transactions and yet the oids are twenty-three consecutive values. Is this the only table you've inserted into during the last 400K transactions? It's also odd that there's so much empty space (only 37 rows in 60 pages). It's hard to see how that could be unless there were many updates on the table, but judging from the name and contents of the table I can hardly see a reason for lots of updates. How is this table used exactly? Do you do UPDATEs on it? DELETEs? SELECT FOR UPDATE? Do you do VACUUM, or VACUUM FULL, or both? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
