Hi
I want to find some architectural information about the storage
subsystem of PostgreSQL especially the modulus which are responsible to
loading data from disk to the Shared Buffer. I cannot find any
structured and useful information on web.
Would you please help me to find such information.
Should I read the source code?
Which part of code is responsible to reading data from the disk?
Regards
Javadi
