Hello,
I have been working with Postgresql for the last 3 years. Before that
I worked with Oracle, Mysql and other databases.
Now, its time to learn the internals of Postgresql system. I
downloaded the source code and imported it in my eclipse environment.
But I have very limited knowledge on C programming.
Could you guys please guide me from where I should start?
If you really want to start messing with the Pg innards, and you have
already read and understood all the developer documentation, I'd suggest
starting by writing some simple user defined functions in C. Write a
simple function that returns a plain value. Then a record. Then a set of
records. Then write an aggregate function. Then a window function. Dig
into the data structures and types. When you're game, implement a simple
data type. Then add support for indexing it. etc.
Honestly, if you don't have something you want to _achieve_ it's
probably mostly going to be boring. What do you want to do, to get out
of this?
