      Creates a named savepoint.

      Savepoint names need to be valid Firebird identifiers, and the maximum length is restricted to the maximum identifier length (see `DatabaseMetaData.getMaxColumnNameLength()`. The implementation will take care of quoting the savepoint name appropriately for the connection dialect. The `name` should be passed unquoted.

      With connection dialect 1, the name is restricted to the rules for unquoted identifier names, that is, its characters are restricted to `A-Za-z0-9$_` and handled case insensitive.

      For dialect 2 and 3, the name is restricted to the rules for Firebird quoted identifiers (essentially any printable character and space is valid), and the name is handled case sensitive.
