When running postgresql inside gdb, I have always found it difficult to
dump out structures. Here is something I found, that I have added to
the developers FAQ:
---------------------------------------------------------------------------
You can print nodes easily inside gdb. First, to disable output
truncation:
(gdb) set print elements 0
You may then use either of the next two commands to print out List,
Node, and structure contents. The first prints in a short format, and
the second in a long format:
(gdb) call nodeToString(any_pointer)
(gdb) call pprint(any_pointer)
