Hi. Traditionally, to generate a TSV report, I've simply invoked psql with: --no-align --field-separator '\t' --pset footer=off That works in most cases, except when your column values contain tabs themselves. I know that COPY() will escape tabs (as \t), and we can use that from psql with the \copy command, but that does not include a header row of the column names. So, my question is, what's the simplest way to generate tab-escaped TSV-formatted reports with the first line containing the list of column names?
create table tsv_test (id int, fld_1 varchar); insert into tsv_test values (1, 'test value'); insert into tsv_test values (2, 'test value'); insert into tsv_test values (3, 'test value'); \copy tsv_test to 'data.tsv' with csv header delimiter ' '; aklaver@panda:~> cat data.tsv id fld_1 1 "test value" 2 "test value" 3 "test value"
I also considered handling the escaping myself within the SELECT, and then sticking with the first approach above. Suggestions? Thanks.
