I maintain images (from Webcams). In the Java and Hibernate (JPA) code I specified a @Lob annotation on class MyData and a attribte/data type "byte[] mydata;". Hibernate then generates two tables in PostgreSQL, one called MyData with a column mydata of type oid and an internal one called pg_largobjects (which contain foreign keys to the oid). That's also explained in the JDBC docs [1], saying "PostgreSQL provides two distinct ways to store binary data. Binary data can be stored in a table using the data type bytea or by using the Large Object feature which stores the binary data in a separate table in a special format and refers to that table by storing a value of type oid in your table."
I think you are better off using bytea unless you need to access only parts of the blob regularly. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
