|

* Remove 'isViewRule' since we check the relkind when getting tables.
|
||||
* Now uses temp table 'pgdump_oid' rather than 'pg_dump_oid' (errors otherwise).
|

|
||||
* Modifications - 02-Oct-2000 - pjw@rhyme.com.au
|
||||
*
|
||||
* - Be more paranoid when getting views: call get_viewdef in separate statement
|
||||
* so we can be more informative in error messages.
|
||||
* - Support for 'isstrict' procedure attribute.
|
||||
* - Disable --blobs and --table since (a) it's a pain to get ONLY the blobs for the
|
||||
* table with the currently implementation, and (b) it's not clear how to restore
|
||||
* a partial BLOB backup (given the current OID-based BLOB implementation).
