The accepted solution didn't work for me.

Install GDAL/OGR using OSGeo4W, and in Advanced Install mode select gdal-oracle10g.

Then execute this command:

ogr2ogr 
-a_srs {{SRS}} 
-overwrite -f 
"PostgreSQL" 
-nln {{POSTGIS SCHEMA}}.{{POSTGIS TABLE}} 
PG:"
host='{{POSTGIS HOST}}' 
port='{{POSTGIS PORT}}' 
user='{{POSTGIS USER}}' 
password='{{POSTGIS PASSWORD}}' 
dbname='{{POSTGIS DATABASE}}'" 
OCI:"{{ORACLE USER}}/{{ORACLE PASSWORD}}
@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
(HOST = {{ORACLE HOST}})
(PORT = {{ORACLE PORT}})))
(CONNECT_DATA = (SID = {{ORACLE SID}})))
:{{ORACLE SCHEMA}}.{{ORACLE TABLE}}"

replace {{ }} items with your values!

You need to do this for each table. There is an spreadsheet that can generate these commands for you:
