Description

We have two problems here:

1. Cannot drop schema madlib and re-deploy MADlib in schema madlib

2. pg_dump skip dumping content of schema madlib/retail_demo, which should be dumped by default actually. To skip dumping some schema, you can specify it in command line option of pg_dump. Details below:

[gpadmin@localhost bin]$ pg_dump --help

  -F, --format=c|t|p       output file format (custom, tar, plain text)
  -i, --ignore-version     proceed even when server version mismatches
                           pg_dump version
  -v, --verbose            verbose mode
  -Z, --compress=0-9       compression level for compressed formats

                              use SESSION AUTHORIZATION commands instead of
                              ALTER OWNER commands to set ownership
  --gp-syntax                 dump with Greenplum Database syntax (default if gpdb)
