[BUG] JSQLParser 5.4-SNAPSHOT : PostgreSQL : "generated always as" regression in 5.4-SNAPSHOT

[LouizFC]

Always check against the Latest SNAPSHOT of JSQLParser and the Syntax Diagram

Failing SQL Feature:

• 5.4-SNAPSHOT currently introduces a regression: "generated always as" or "generated by default" makes the parser fail when encountering the keywords in create table statements, previously (5.3) this information was just added to ColumnDefinition#getColumnSpecs

SQL Example:

• Simplified Query Example, focusing on the failing feature

create table if not exists book_type (
  id bigint not null generated always as identity
);

throws
