[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=13520220#comment-13520220 ] 

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

I've attached an extract of log that contains the sql its trying to execute.  [^information_schema.log] 

> Ah, I had only checked on the pg_ tables mentioned in the issue. That would require an additional system schema, so we'll have to give some thought to the ramifications.

I was hoping the pg_ tables would have been sufficient to generate the meta information for tables and views, but it seems the provider uses the information_schema instead. Doing some research it seems there is a way to use PowerBi advance query features to extract the data vs using the wizards.

If you agree I think this issue can still be marked as resolved because these changes does allow for a session to be created and queries be executed against any vdb using the npgsql provider. A separate issue can be created for tracking the information_schema support so meta information can be queried.
