PostgreSQL parser error

[Niax23]

• Error Description
  After successfully configuring the LLM and database, when attempting to use CrackSQL's translate.py to convert PostgreSQL statements, the program encountered an error during parsing of the PostgreSQL statement as shown below:

• Root Cause:
  In the file ./CrackSQL/backend/preprocessor/antlr_parser/pg_parser/PostgreSQLParser.py, line 35398 the ParseRoutineBody function was undefined. The call of this function will certainly bring about error.

• Temporary Solution:
  After commenting out this line, the program ran successfully without obvious bug.

I think the tiny change of the code will make the repo better. However, I'm not sure that whether this solution is robust and elegant. Thanks, and looking forward to your insights!

@Niax23 Thanks for your reports.
This issue is duplicated at #7. It is relevant to the generated ANTLR parser, not CrackSQL. There also exist one PR to resolve this issue at #19. You can consider to replace the files in the PR to see if such issue persists.
