schemas not appearing in pgAdmin

I'm running postgres 8.0.3 (Solaris) and PgAdmin III 1.8.0

I created a schema in my prod DB that is named pgmacdon, however it 
appears that pgAdmin III is not displaying this schema as existing in the 
prod DB.

It would appear that you are using the wrong query to exclude the pg_* 
internal schemas

PgAdmin III appears to be doing a query similar to the following to 
retrieve the list of schemas to display:

SELECT nspname, CASE WHEN nspname LIKE 'pg\_tmp\_%%' THEN 1      WHEN (nspname LIKE 'pg\_%') THEN 0      ELSE 3 END AS
nsptyp
FROM pg_namespace

      nspname       | nsptyp
--------------------+-------- pg_toast           |      0 pheller            |      3 pg_temp_1          |      0
pg_catalog        |      0 public             |      3 mdpeters           |      3 information_schema |      3 dfonda
         |      3 msessums           |      3 adbrown            |      3 philmacdonald      |      3 pgmacdon
|      0  <===== FALSELY being set to 0 (don't display)
 


It would appear that in order to match pg_*, postgres requires:

LIKE 'pg\\_%'
_rather than_
LIKE 'pg\_%'

Not sure if this was a bug in 8.0.3 that was later fixed or the syntax for 
a literal underbar MUST BE '\\_'
