This can also happen with cursor operations where a FETCH operation is performed, but no row is returned. To diagnose and fix this …
The HV001 error code in PostgreSQL is associated with a foreign data wrapper (FDW) and signifies that the FDW has encountered an out-of-memory condition. This error typically occurs when the FDW is unable to allocate the memory it needs to perform its operations, which might be due to the PostgreSQL server’s memory constraints, the host …
The HV091 error code in PostgreSQL is related to a foreign data wrapper (FDW) and indicates that there is an invalid descriptor field identifier.

The P0000 error code in PostgreSQL, marked as plpgsql_error, is a generic error code indicating that an error has occurred in a PL/pgSQL block, which is not covered by any specific SQLSTATE code. Since P0000 is not very descriptive, diagnosing and fixing issues associated with this error code requires a closer look at the context …
The HV00P error code in PostgreSQL, which signifies fdw_no_schemas, indicates that an attempt was made to import a schema from a foreign server, but no schemas were available to be imported. This issue typically arises when using the IMPORT FOREIGN SCHEMA command and can be due to various reasons, such as incorrect permissions, the non-existence …
The HV00C error code in PostgreSQL is related to an fdw_invalid_option_index issue, which indicates a problem with the index of options provided to a foreign data wrapper (FDW). This error is less common and typically suggests that there’s a configuration issue with the options specified for the FDW, such as an invalid option name or …
The HV010 error code in PostgreSQL corresponds to an fdw_function_sequence_error, which is related to foreign data wrappers (FDWs). This error typically occurs when there is an issue with the sequence of functions being called on a foreign data wrapper. For instance, it can happen if a function that requires a prior action to be called …
The P0003 error code in PostgreSQL, which stands for too_many_rows, indicates that a query that is expected to return only one row has returned more than one row.
