+# Print The Query Buffer In psql
+
+I'll often be composing a PostgreSQL query in Vim and decide I want to give
+it a try in `psql`. I copy the relevant snippet of SQL to my system buffer
+and then paste into `psql`. I'm usually hit with a mess of text like this
+though:
+
+```sql
+jbranchaud=# create table nullable_fields (
+jbranchaud(#   id serial primary key,
+  first varchar,
+  last varchar
+)
+  id serial primary key,
+jbranchaud(#   first varchar,
+  last varchar
+)
+  first varchar,
+jbranchaud(#   last varchar
+)
+  last varchar
+jbranchaud(# )
+)
+jbranchaud-#
+```
+
+Yikes. That's not readable. Fortunately, `psql` provides a command for
+printing the current contents of the query buffer. By typing `\p` I'll see a
+more readable version of what I just pasted in.
+
+```sql
+jbranchaud-# \p
+create table nullable_fields (
+  id serial primary key,
+  first varchar,
+  last varchar
+)
+jbranchaud-#
+```
+
+After taking another glance at the snippet of SQL, I decide to complete the
+query to create my new table.
+
+```sql
+jbranchaud-# ;
+CREATE TABLE
+```
