Intenté empujar algunas evoluciones a Heroku:

Estas evoluciones funcionarán bien con el H2, supongo que debe haber algunos problemas con la sintaxis POSTGRESQL. De todos modos, el problema que tengo ahora es que, incluso si cambio 1.sql y presiono la nueva versión en Heroku, aparecerá el mismo error en los registros: el 1.sql copiado no cambia según la nueva versión implementada .
