When do Postgres column or table names need quotes and when don't they?
Let's consider the following postgres query: SELECT * FROM "MY_TABLE" WHERE "bool_var"=FALSE AND "str_var"='something'; The query fails to respond properly when I remove quotes around "str_var" but not when I do the same around "bool_var" . Why? What is the proper way to write the query in that case, no quotes around the boolean column and quotes around the text column? Something else? Orysza Thanks to @TimBiegeleisen's comment, I was able to pinpoint the problem; I used a reserved keyword ("user") as a column name.
