When using Firebird 2.5, the following error occurs:

Unsuccessful metadata update
key size exceeds implementation restriction for index "RDB$PRIMARY23"
Statement:

CREATE TABLE OBD (OBJEKT VARCHAR(20) NOT NULL,
DATEI VARCHAR(180) NOT NULL,
USRINS VARCHAR(8) NOT NULL,
DATINS TIMESTAMP NOT NULL,
USRUPD VARCHAR(8),
DATUPD TIMESTAMP,
TSTAMP TIMESTAMP NOT NULL,
ZUSINFO VARCHAR(40),
FOREIGN KEY (OBJEKT) REFERENCES OBJ,
PRIMARY KEY (OBJEKT,DATEI))

The same statement works fine under firebird 1.5.
