Error in pgdump for pgadmin III 1.8.4

["Panayiotis\(Peter\) Lardos" <plardos(at)tridentglobal(dot)com>]

Dear PGAdmin,

 

When I run pg_dump.exe, I get an error message "server version: 8.3.1;
pg_dump version: 8.3.0". I change my command line with a "-I" option (to
ignore the error/warnings) and that allows my command to run. I also created
a batch file (windows) and that runs fine as well. However, when add the
batch file to the Yosemite backup script, so that it'll run before my backup
job, it fails to execute with an "error 1". Is there a workaround? Can I
upgrade/downgrade my server version to be equivalent to the pg_dump version.

Here is my command for reference:

pg_dump.exe -h server_name -p 5432 -U postgres -F p -o -v -i -f "path" -n
\"public\" "Database"

 

Thanks!
