# This script attempts to find all typedef's in the postgres binaries

# For this program to work, you must have compiled all binaries with
|
|
# debugging symbols.

# This is run on BSD/OS 4.0 or Linux, so you may need to make changes.

|
|
# .stab.excl sections from an ELF file. This is only
|
|
# useful on systems (such as Solaris 2.0) in which
|
|
# .stab debugging symbol-table entries are carried in
|
|
# an ELF section. In most other file formats, debug-
|
|
# ging symbol-table entries are interleaved with
|
|
# linkage symbols, and are visible in the --syms out-
|
|
# put.
