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
I check the postgres's sql compiler, and it's achieved by lex & yacc.
So What type of Compiler to SQL? Is Memory-Image (Load-and-Go) Format ?
Thanks in advance!
Yours,
WenYi
