+
+<para>
+     Originally, <productname>Postgres 4.2</productname> supported three standard 
      implementations of large objects: as files external 
-     to <ProductName>Postgres</ProductName>,  as  <Acronym>UNIX</Acronym>  files managed by <ProductName>Postgres</ProductName>, and as data
-     stored within the <ProductName>Postgres</ProductName> database. It causes

+ <acronym>ym>U</acronym>ym>  files managed by <productname>Postgres</productname>, and as data
+     stored within the <productname>Postgres</productname> database. It causes  
      considerable confusion among users. As a result, we only 
-     support large objects as data stored within  the  <ProductName>Postgres</ProductName>
-     database  in  <ProductName>PostgreSQL</ProductName>.  Even  though it is slower to
+     support large objects as data stored within  the  <productname>Postgres</productname>
+     database  in  <productname>PostgreSQL</productname>.  Even  though it is slower to
      access, it provides stricter data  integrity.
      For historical reasons, this storage scheme is referred to as 
      Inversion large objects. (We will use  Inversion  and  large
      objects  interchangeably to mean the same thing in this
      section.)

      The Inversion large object implementation breaks  large
      objects  up  into  "chunks"  and  stores  the chunks in
      tuples in the database.  A B-tree index guarantees fast
      searches for the correct chunk number when doing random
      access reads and writes.
