Hi team,
I am a newbie to the postgres.
When I am studying the compiler,the text book tell me there is there type of compiler.
  1. Assembly Language Format
  2. Relocatable Binary Format
  3. Memory-Image (Load-and-Go) Format


IIUC (I haven't formally studied compilers), none of the above, or, rather, not applicable.

I can conjure up an analogy that says the assembly language artifact has a similar relationship to the operating system kernel as the compiled plan has to the database executor.
