Thread: pgsql: bootstrap: pure parser and reentrant scanner
bootstrap: pure parser and reentrant scanner Use the flex %option reentrant and the bison option %pure-parser to make the generated scanner and parser pure, reentrant, and thread-safe. Make the generated scanner use palloc() etc. instead of malloc() etc. For the bootstrap scanner and parser, reentrancy and memory management aren't that important, but we make this change here anyway so that all the scanners and parsers in the backend use a similar set of options and APIs.
