- Open Oracle dump with something like notepad++ or grap and do a find/replace for all the binary characters (these can be highlighted in notepad++) and replace them with something like a pipe character ("|")
- If you know the special characters that are not compatible with UTF-8, then do find/replace on these too now ... otherwise you can do this after running the copy command (step 5), since that will give an error for each non UTF-8-able line/character
- Open the piped file in Excel and replace with tabs. Tabs are the standard delimiter in Postgres and by saving out of Excel, you get a uniform number of columns for each record, thereby avoiding "missing data for column" when executing the "copy" command
- Create a table in Postgres with the number of columns seen in Excel, using generic data type such as text
- execute the copy command ... no delimiters param need be given, since it's tabs
COPY data FROM 'C:/temp/data.txt'
