When building SSIS package, I usually write SQL queries for the ODBC Source connecting to a postgres SQL database. Everything works find until today I found when I hit the database access mode as 'SQL Command', there is no command box for me to type. And if I hit the access mode as 'table name' there is no 'preview' button for me to preview the dataset. I have been stuck at this for long time, trying to find why, but was unable to. So I am reaching out to see if you have any insights into this issue? Will this something related to the ODBC driver? fyi, I updated both the pgsql odbc driver and SSIS to their latest versions. 
any inputs will be appreciated!
Thanks,
Kay
