[teiid-issues] [JBoss JIRA] (TEIID-5201) Update teiid pg_type schema to match PostgreSQL pg_type in support of NPGsql provider

[Divyesh Vallabh (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-5201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13517880#comment-13517880 ] 

Divyesh Vallabh commented on TEIID-5201:
----------------------------------------

To test these changes with the npgsql provider I used the baby names example (https://developer.jboss.org/wiki/IntegrateAmazonSimpleDBWithTeiid) created by Ramesh and you.

I was able to create a session as well as successfully query the "file.babies" table from a powershell script I created. I'm attaching the files in case we need to back trace how the connection test was done. [^babynametest.zip] 

However, I'm still having issues with PowerBi when using the Npgsql provider. From the Teiid logs it looks like its querying "information_schema" namespace for table and column information. 

Looking at the Npgsql github code its referencing the *information_schema.tables*, *information_schema.columns* and *information_schema.views* tables. 

I also noticed that it issued the following sql command "UNLISTEN *" as well.
