Use StringInfo to build the result in oidvectortypes() Replace manual buffer management with StringInfo to avoid repeatedly scanning the accumulated output when appending type names. This removes quadratic scanning for large input vectors and simplifies the code.
Also check for interrupts in the loop and free temporary type names after appending them to the result.
