Hi, I have a few questions about the storage and performance 1. How do you estimate the table size in postgresql? For example if I have a table 'Dummy' with 1 varchar (3) & 1 numeric(8,0) fields and 1000 rows, what is the tablesize estimate for this (including the row overhead etc)? How many pages will this occupy? 2. Also if the table contains null columns, does postgres allocates the same space for these nulls columns? How does it handle 'nulls' in terms of storage? 3. How does oracle handle these 2 cases? 4. Does increasing the block size in postgres improve query performance? Thanks in advance Josh ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
