Hello, I have a software that uses Posgtres 8.4.2 on Windows. I have a database with data splitted into schemas, so that every schema replicates the same set of tables. One of the table is called "code": it has 16 columns, almos all numerics except for a carachtervarying(1024) and two text fields. It holds usually a few thousands record at most, then the file size of the table is usually around few hundred kbytes. In only one case so far, the "code" table with 442 record has a size of 18MB. If I run an vacuum full and a reindex it shrinks to less than 100KB. If I use the software to delete the rows and reinsert the same records it explodes again to 18MB. I have backed up the table (from a WIndows7 instance running on a virtual machine) and recovered it on another database (running on a"real" Windows Vista) and tried the same things with the same results. Then I have dropped the table, recreated it and reinserted the records: the anomaly has disappeared. I really don't know what to look for. I cannot ignore the problem because schemas are created by the software on software users request and it could reappear in any schema. I really don't have a clue: I would be happy to further study the problem but I don't know in which direction I have to go. Can someone point me in some (hopefully good) direction? -- ================================================== dott. Ivano Mario Luberti Archimede Informatica societa' cooperativa a r. l.
