Hello, i begin to learn how to admin a postgreSQL database.
I would like to know some things like :
How do you calculate the length of a record in a table ?
How do you estimate the access time to a data in a table ?
How many records can i insert in this database (before the system
falls down) ?
If you had to insert a multimedia file (.wav) in this database, would
you do it or not ?
And where can i find these information ? (i read FAQ and technotes, no
results...)
Thanks a lot.
