Обсуждение: quoted variables in pgsql

cannot figure this out

# \set var 'value'
# select * from some_table where some_col = :var;
ERROR: column value does not exist

cannot get those quotes around the value.  tried:
# \set var ''value''
# \set var ''''value''''

in each case:
# \echo :var
value

thanks

Use backslashes.

regression=# \set var '\'value\''
regression=# \echo :var
'value'
