InvalidOperationExceptionReason

Transaction operations like commit or savepoint used when auto-commit is enabled.

Provided savepoint is invalid or belongs to another connection.

The handle being used is closed or finished - a statement, a Large Object, a COPY that has already ended. Handles are not reopened; details names the one at fault and the answer is always a new one.

An argument supplied by the caller is not acceptable - out of range, null, or unsupported. Covers negative timeouts, a null SQL string, an unknown isolation level, a PgTyped wrapping another PgTyped, a PgRecord read out of a result and handed back as a bound parameter, and the like. The offending value is named in details; there is nothing to branch on here, since no caller can react to its own bad argument at runtime.

The statement names a parameter the supplied values do not include. A @name with nothing to put there is the call being incomplete rather than the SQL being wrong, which is why it is here and not on StatementException; details names the parameter.

JDBC unwrap() failed.

The JDBC feature is not implemented by this driver.

update or execute returned result.

The query returned a number of rows the chosen terminal forbids - a fetch*Strict that found none, or a single-row fetch that found several. The statement ran; what does not fit is the terminal picked for it, which makes this UNEXPECTED_RESULT's neighbour rather than a statement failure.

The connection is already carrying an exchange and can carry only one - a COPY still running, or a statement still being read. details says which, and what to do about it.
