Why Does My Database Query Return 'Relation '[TABLE] Does Not Exist' Even Though the Table Appears to Exist?

Error: Relation "Table" Does Not Exist: A Persistent Enigma

In the realm of database queries, encountering the error "relation [TABLE] does not exist" can be a puzzling experience, especially when the table in question appears visible in the server explorer. To resolve this issue, it is crucial to understand why the tables cannot be properly queried.

The problem often stems from inappropriate syntax in specifying table names and schemas. In PostgreSQL, elements such as schemas and table names must be enclosed in double quotes to be recognized as strings. Failing to do so can lead to the elusive "relation does not exist" error.

To rectify this mistake, ensure that each individual element is enclosed within double quotes, as illustrated below:

select "ID" 
from "Schema"."table1";

By precisely quoting each component, the query can correctly identify the target table and retrieve the desired data.

Detailed information regarding the proper usage of quoted identifiers can be found in the official PostgreSQL documentation.
