You should report this bug to the jOOQ code generator as the generated code is wrong IMO. The @Column annotation documents that the precision member is only used for decimal/numeric column types, so it kind of implies that the unit is in number of decimal digits. Hibernate 5 ignored this member so far, but in Hibernate 6, we support interpreting the precision member, but we decided to not change the unit to suddenly mean binary digits just because a float/double java type is used. Since 53 is the default precision for double, the member should just be omitted. The closest you can get with decimal numbers is by using a precision of 15 which will result in a binary precision of 50. Using a precision of 16 would result in a binary precision of 54, which might not be supported on all databases. If you want to be in full control of your schema, use a tool like Liquibase or Flyway.
