ERROR: COPY delimiter must be a single one-byte character

Question

I want to load the data from a flat file with delimiter "~,~" into a PostgreSQL table. I have tried it as below but looks like there is a restriction for the delimiter. If COPY statement doesn't allow multiple chars for delimiter, is there any alternative to do this?

metadb=# \COPY public.CME_DATA_STAGE_TRANS FROM 'E:\Infor\Outbound_Marketing\7.2.1\EM\metadata\pgtrans.log' WITH      DELIMITER AS '~,~'
ERROR:  COPY delimiter must be a single one-byte character
\copy: ERROR:  COPY delimiter must be a single one-byte character

If you are using Vertica, you could use E'\t'or U&'\0009'

To indicate a non-printing delimiter character (such as a tab), specify the character in extended string syntax (E'...'). If your database has StandardConformingStrings enabled, use a Unicode string literal (U&'...'). For example, use either E'\t' or U&'\0009' to specify tab as the delimiter.
