First of all, this is not a topic for the novice mailing list, rather
for the hackers one.
By I warn you, before asking there, you should have a look at the
documentation about PostgreSQL for developers and try to attach a
debugger to a live session in order to see what is happening behind
the scene.
In the meantime start reading all the READMEs in the backend source
tree, have a look at PageAddItem in storage/page/bufpage.c and
_bt_doinsert in access/nbtree/nbtinsert.c, this should give you an
idea about your questions.
