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.
