I found this hint about 'pg_cursors' in stackoverflow:
https://stackoverflow.com/questions/51146931/postgres-finding-an-open-cursor-and-closing-it
But did no see how to code this in ESQL/C, something like:
EXEC SQL IF EXISTS(SELECT * FROM pg_cursors WHERE name = :cur) THEN CLOSE :cur;
Which does not work. And, what concerns me as well is how expensive such
test is before closing any cursor.
