we have a question about the pagesize in PostgreSQL:
Using different pagesizes: 4K, 8K, 16K, 32K, when we store different record sizes
such as in the following example:
CREATE TABLE TEST_1 ( F1 VARCHAR(10), F2 VARCHAR(5) );
CREATE TABLE TEST_2 ( F1 VARCHAR(10), F2 VARCHAR(10) );
we're consistently having the following storage behavior:
60 records / 4k_page 120 records / 8k_page 240 records / 16k_page 480 records / 32k_page.
So it seems that it doesn't matter whether the record size is 15 bytes or 20 bytes, there's maximum number of records per page as shown above.
Any clues if there's any parameter or bug causing that?
