PostgreSQL Error HV00A: FDW Invalid String Format
Description
This error indicates that the Foreign Data Wrapper (FDW) encountered a string value from the foreign server that could not be interpreted or converted correctly into the expected format or data type within PostgreSQL. It typically arises during data retrieval or insertion operations involving foreign tables.
Error Message
fdw invalid string format
Known Causes
4 known causesData Type Mismatch
The data type defined for a column in the PostgreSQL foreign table does not match the actual string format or data type of the corresponding column on the foreign server.
Incorrect FDW Options
The `OPTIONS` specified during the creation of the foreign table or server (e.g., `format`, `encoding`, `quote_char`) are not compatible with the foreign data source's string representation.
Encoding Inconsistencies
A mismatch in character encoding between the PostgreSQL server, the FDW, and the foreign data source leads to misinterpretation of string data.
Malformed Foreign Data
The foreign data source itself contains malformed or unparseable string values that the FDW cannot process according to its configured rules.
