Обсуждение: Very large table...
Does anyone have any experience with very large postgresql tables? By very large, I mean a table with ~38 million records, each record will have between 80 and 128 bytes (we are not sure of some column sizes yet) in ~10 columns with probably 3 btree-indexes. Basically the table will hold all of the Postal Service deliverable addresses in the US in a somewhat compressed form. My concerns are in the area of performance and robustness. I know I haven't been specific enough about the table layout, but I am not sure yet exactly what it will look like. I am just try to get a gut level feeling that this has been done before and there are no "got'chas" out there. Thank you all, Jeff

Should be OK as long as you are using a recent release (preferably 7.0). Our support for tables over 2 gig used to be a little flaky, but it's been wrung out... regards, tom lane
