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

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-5201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13517886#comment-13517886 ] 

Steven Hawkins commented on TEIID-5201:
---------------------------------------

> 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.

Can you provide the log?

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

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

Ignoring an unlisten won't be problem, but if it's expecting events from listen that would be an issue as that feature is not implemented.
