The following bug has been logged on the website:
Bug reference: 9620
Logged by: Nicolas Payart
Email address: postgresql(at)htmledit(dot)com
PostgreSQL version: 9.3.3
Operating system: Linux Debian 7.4
Description:
When using short option "-i" with option "--globals-only", pg_dumpall dumps
all databases (structure and data) instead of just global objects:
pg_dumpall -i --globals-only
Using long option "--ignore-version" with "--globals-only" is ok:
pg_dumpall --ignore-version --globals-only
This problem is present on my 9.3.3 instance and is not reproducible on
older versions (9.2.7 for example).
