It seems PostgreSQL does not allow to create a database table named 'user'. But MySQL will allow to create such a table.
Is that because it is a key word? But Hibernate cannot identify any issue (even if we set the PostgreSQLDialect).

user is a keyword; "user" is a user-defined identifier that's a legal table name.
PostgreSQL: Find Users in PostgreSQL Answer: In PostgreSQL, there is a system table called pg_user. You can run a query against this system table that returns all of the Users that have been created in PostgreSQL as well as information about these Users.
Table names are by convention lowercase and pluralized with multi-word table names separated by underscores. For example, a Model name of Ingredient expects the table name ingredients .
user is a reserved word and it's usually not a good idea use reserved words for identifiers (tables, columns).
If you insist on doing that you have to put the table name in double quotes:
create table "user" (...); But then you always need to use double quotes when referencing the table. Additionally the table name is then case-sensitive. "user" is a different table name than "User".
If you want to save yourself a lot of trouble use a different name. users, user_account, ...
More details on quoted identifiers can be found in the manual: http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS

It is possible to specify tablename with JPA with next syntax:
@Table(name="\"user\"") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
