Subject: [PATCH v5 1/2] Add 'noError' argument to encoding conversion
functions.
With the 'noError' argument, you can try to convert a buffer without
knowing the character boundaries beforehand. The functions now need to
return the number of input bytes successfully converted.
This is is a backwards-incompatible change, if you have created a custom
encoding conversion with CREATE CONVERSION. This adds a check to
pg_upgrade for that, refusing the upgrade if there are any user-defined
encoding conversions.
Add regression tests for built-in encoding conversions. This doesn't cover
every conversion, but it covers all the internal functions in conv.c that
are used to implement the conversions.

Subject: [PATCH v5 2/2] Do COPY FROM encoding conversion/verification in
larger chunks.
NOTE: This changes behavior in one corner-case: if client and server
encodings are the same single-byte encoding (e.g. latin1), previously the
input would not be checked for zero bytes ('\0'). Any fields containing
zero bytes would be truncated at the zero. But if encoding conversion was
needed, the conversion routine would throw an error on the zero. After
this commit, the input is always checked for zeros.

* copyfromparse.c
* Parse CSV/text/binary format for COPY FROM.
*
+ * This file contains routines to parse the text, CSV and binary input
+ * formats. The main entry point is NextCopyFrom(), which parses the
+ * next input line and returns it as Datums.
+ *
+ * In text/CSV mode, the parsing happens in multiple stages:
+ *
+ * [data source] --> raw_buf --> input_buf --> line_buf --> attribute_buf
+ * 1. 2. 3. 4.
+ *
+ * 1. CopyLoadRawBuf() reads raw data from the input file or client, and
+ * places it into 'raw_buf'.
+ *
+ * 2. CopyConvertBuf() calls the encoding conversion function to convert
+ * the data in 'raw_buf' from client to server encoding, placing the
+ * converted result in 'input_buf'.
+ *
+ * 3. CopyReadLine() parses the data in 'input_buf', one line at a time.
+ * It is responsible for finding the next newline marker, taking quote and
+ * escape characters into account according to the COPY options. The line
+ * is copied into 'line_buf', with quotes and escape characters still intact.
+ *
+ * 4. CopyReadAttributesText/CSV() function takes the input line from
+ * 'line_buf', and splits it into fields, unescaping the data as required.
+ * The fields are stored in 'attribute_buf', and 'raw_fields' array holds
+ * pointers to each field.
+ *
+ * If encoding conversion is not required, a shortcut is taken in step 2 to
+ * avoid copying the data unnecessarily. The 'input_buf' pointer is set to
+ * point directly to 'raw_buf', so that CopyLoadRawBuf() loads the raw data
+ * directly into 'input_buf'. CopyConvertBuf() then merely validates that
+ * the data is valid in the current encoding.
+ *
+ * In binary mode, the pipeline is much simpler. Input is loaded into
+ * into 'raw_buf', and encoding conversion is done in the datatype-specific
+ * receive functions, if required. 'input_buf' and 'line_buf' are not used,
+ * but 'attribute_buf' is used as a temporary buffer to hold one attribute's
+ * data when it's passed the receive function.
+ *
+ * 'raw_buf' is always 64 kB in size (RAW_BUF_SIZE). 'input_buf' is also
+ * 64 kB (INPUT_BUF_SIZE), if encoding conversion is required. 'line_buf'
+ * and 'attribute_buf' are expanded on demand, to hold the longest line
+ * encountered so far.
