From the advanced bikeshedding department: I'd like my psql transcripts to have the usual alignment, but be easier to copy and paste later without having weird prompt stuff in the middle. How about a prompt format directive %w that means "whitespace of the same width as %/"? Then you can make set your PROMPT2 to '%w ' and it becomes invisible:
pgdu=# create table foo ( i int, j int ); CREATE TABLE pgdu=#
