I believe using the PostgreSQL array type might help,

Instead of declaring your iFilter parameter as TEXT, declare it as ARRAY.
Then instead of 'CADRG, DTED1, DTED2, SRTF' you would put the input
parameter as '{"CADRG", "DTED1", "DTED2", "SRTF"}'
And then change cat.type in (iFilter) to cat.type = ANY (iFilter)
Good luck.
