Hello,

I am using Liquibase with postgres JDBC driver postgresql-8.4-702.jdbc4.jar
PostgreSQL - 8.4.4
My table structure, for example, is
CREATE TABLE applications
(
  id character varying NOT NULL,
  "name" character varying NOT NULL,
  "version" character varying NOT NULL,
)

When i try export my database structure to the Liquibase script it makes
column with length 2147483647.
            <column name="id" type="VARCHAR(10485760)">
                <constraints nullable="false" primaryKey="true"
primaryKeyName="applications_pkey"/>
            </column>
Maximum length of type character varying is 10485760.
Generated script is broken.

I looked at Liquibase code and found that ResultSet.getInt("COLUMN_SIZE")
returns 2147483647 when length not set implicitly.

Is this a bug?
Is there any workaround exist?

You can set the unknownLength URL parameter to say whay you think the size of an unspecified string should be:
