> Incomplete quoting of SQL identifiers in AlterTableConstantAction

> AlterTableConstantAction generates SQL statements various places. Identifiers
> (schema names, table names, column names) are surrounded with double quotes
> in case they contain special characters. This is not enough if the
> identifiers contain double quotes, as can be seen with this example:
> ij> create table t(x int);
> 0 rows inserted/updated/deleted
> ij> alter table t add column """" int default 42;
> ERROR 42X01: Syntax error: Encountered "\"" at line 1, column 22.
> I've found three places where AlterTableConstantAction generates SQL
> statements: updateNewColumnToDefault(), updateNewAutoincrementColumn(),
> getColumnMax(). All three places suffer from this problem.
