Why PostgreSQL DOCs needs to show or compare the Oracle way of doing things ?
I understand that on page Porting from Oracle PL/SQL is ok to mention Oracle, but there are other places where it's not needed. Or, if it's ok to mention, why not mention SQL Server or MySQL or any other ?
Bug Reporting Guidelines
Especially refrain from merely saying that “This is not what SQL says/Oracle does.”
LOCK
the PostgreSQL lock modes and the LOCK TABLE syntax are compatible with those present in Oracle.
SELECT
Applications written for Oracle frequently use a workaround involving the automatically generated rownum column, which is not available in PostgreSQL, to implement the effects of these clauses.
ROLLBACK TO SAVEPOINT
The SQL standard specifies that the key word SAVEPOINT is mandatory, but PostgreSQL and Oracle allow it to be omitted
Data Type Formatting Functions
FM modifies only the next specification, while in Oracle FM affects all subsequent specifications, and repeated FM modifiers toggle fill mode on and off.
Data Type Formatting Functions
A sign formatted using SG, PL, or MI is not anchored to the number; for example, to_char(-12, 'MI9999') produces '- 12' but to_char(-12, 'S9999') produces ' -12'. (The Oracle implementation does not allow the use of MI before 9, but rather requires that 9 precede MI.)
