Long: `Start a PostgreSQL wire protocol compatible database server that provides SQL query access to SeaweedFS.
This database server enables any PostgreSQL client, tool, or application to connect to SeaweedFS
and execute SQL queries against MQ topics. It implements the PostgreSQL wire protocol for maximum
compatibility with the existing PostgreSQL ecosystem.

# Start with MD5 authentication
weed postgres -auth=md5 -users="user1:pass1,user2:pass2"
weed db -auth=md5 -users="user1:pass1,user2:pass2"
# Start with custom port and master
weed postgres -port=5433 -master=master1:9333
weed db -port=5433 -master=master1:9333
# Allow connections from any host
weed postgres -host=0.0.0.0 -port=5432
