#35361)

**Description**

When the user tries to add a postgres datasource and add any query, if
the table name has hyphens in it, then quotes get assigned to first word
after the schema and the dot. For example, public."counter"-with-db
The quotes should be applied to the whole table name. For example:
public."counter-with-db"
