parse tree reading

[Katherina Litvina <katherinaniv@xxxxxxxxx>]

In order to implement the incremental updates of materialized views I need to read parse trees from csv logs (debug_print_parse option). How can I interpret the indexes of all operations and tables and get the real names of all relations?

For example, which data and operation types do the values 1760 and 1700 refer to?
OPEXPR 
         :opno 1760 
         :opfuncid 0 
         :opresulttype 1700 
         :opretset false 
Best regards,
