> The number of tables is irrelevant, Not necessarily ... if you are using a filesystem in which directory lookups in large directories are inefficient, you could have a problem, since each table will correspond to a file within the database directory. If you're planning on having more than a few thousand tables you'll want to choose a filesystem that copes well with large directories. But having said that, an application that needs several thousand distinct tables is usually an application that needs a redesign. Consider folding the data into fewer tables with more key columns. 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
