有人用这个工具吗?我想从我的数据库中生成一个 ER 图。我像这样运行 SchemaSpy:
java -jar schemaSpy_5.0.0.jar -t pgsql -db mydb -host localhost -dp /home/katie/downloads/postgresql-8.0-312.jdbc3.jar -noschema -u postgres -o .
然后,我得到了错误:
Using database properties:
[schemaSpy_5.0.0.
jar]/net/sourceforge/schemaspy/dbTypes/pgsql.properties
Gathering schema details..........................................................java.sql.SQLException: ERROR: function information_schema._pg_keypositions() does not exist
