PostgreSQL Error 42809: Wrong Object Type Query
Description
This error indicates that an SQL statement is attempting an operation on a database object that is not compatible with that operation. It typically arises from syntax errors where the command expects one type of object (e.g., a table) but is given another (e.g., a view, sequence, or function), or when referencing a non-existent object.
Error Message
wrong object type
Known Causes
3 known causesIncorrect Command for Object Type
An SQL DDL (Data Definition Language) command is applied to a database object of an incompatible type, such as attempting to use `ALTER TABLE` on a `VIEW` or `DROP SEQUENCE` on a `FUNCTION`.
Non-existent or Misspelled Object
The SQL statement references an object name that either does not exist in the database or contains a typo, leading PostgreSQL to fail in identifying the correct object type.
Schema Path Mismatch
The target object exists, but the current `search_path` or explicit schema qualification in the SQL statement prevents PostgreSQL from locating it correctly within the database.
